Plot hole: The facehuggers "see" by reading body heat, but this contradicts nearly every other film in which the creatures appear. In the original film they can see Kane's face through a space suit and helmet, so it must be tracking more than just body heat. The creatures also routinely leap directly at their victim's faces. This suggests that they "see" facial detail in some way that goes beyond simply reading body heat. The protagonists should not be completely invisible just by hiding their body heat.
Suggested correction: The thorax and chest cavity is the warmest part of the body. It's tracking the heat from your breath and see's it as an opening down to the chest cavity. Which is why it always latches onto the face. It helps when the victim screams too. More heat.
It can't read Kane's body heat through a space suit, and his breath isn't escaping from his helmet at his mouth. It leaps directly at his face and melts through the helmet to get where it needs to go. The intent in the original film is that the creatures can see, not just read body heat. Additionally, we see from the xenomorph perspective in Alien 3 and Alien Covenant and their vision is not based on body heat. The heroes are invisible here just by raising room temperature.
Where has it ever been stated that they can't read Kane's body heat through a space suit? They're literally showing you it can. That's not a mistake of the movie. Alien 3 happened after this movie. Alien Covenant's praetomorph was created by David. So not the same situation as this. This is also someone speculating based off observation and study vs. A camera trick of showing their actual vision in events that haven't happened yet or on another planet. So they could be wrong.
It's a space suit, they are insulated. That's why when you wear a space suit the lack of atmosphere doesn't kill you. There's no possible way creatures that only see heat could see a human through a space suit. That's a mistake for THIS movie and this movie alone because this is the only instance where heat vision is suggested. The fact that earlier released films take place later in the mythos doesn't really change anything, this film makes a claim unsupported by the other films.
There was wind and ice on that planet. That constitutes an atmosphere. Kane is in a giant helmet, leaning fully over the egg opening as it hatched. That was pretty much the only place it could go. Just because the suit is insulated from the cold atmosphere on the outside, doesn't mean the suit itself can't get hot from the heat inside. Also, these are aliens, I never get trying to apply human logic to a fictional being from another planet, in the future, that survives in an atmosphere we can't.
There is some atmosphere on LV-426, but that is entirely missing the point. The space suit is designed to be worn in no atmosphere, so it is insulated. Space is incredibly cold; if your body heat could be drawn to the surface of a space suit, you would freeze to death in minutes while wearing one in space. You can't read someone's body heat through a space suit. I am not trying to apply "human logic" to an alien; I am saying this film contradicts the others. Thus, it is a plot hole.
You're missing the point. Kane leaned over the opening in a giant helmet, inches from the creature. Where else was the facehugger going to jump to? You keep saying, "you can't read someone's body heat"; that's based off current human knowledge and our abilities, not the abilities of a fictional alien creature who lives in the cold reaches of space. You can't say what it can or cannot do when it is showing you that it can.
We can absolutely say what the creature can and can't do based on what has been shown countless times throughout 40-plus years of canon media. This film makes a claim to create a tense scene. That scene contradicts what we know about the creatures. There has never been any indication that they see based on heat, and implying that they do does not follow how we see them behaving in basically every other appearance. Them "showing us that it can" is the mistake; that's, by definition, a plot hole.
Why do you refuse to answer my question? Kane leaned over the opening in a giant helmet, inches from the creature. Where else was the facehugger going to jump to?
To answer your question: How does it know anything is even there? They see by heat, and the characters in this film are invisible just by raising room temperature. It shouldn't know that Kane is even in the room. So where else should it have jumped? Nowhere; he should be invisible according to this film. It shouldn't have jumped at all.
Suggested correction: Someone in a spacesuit has the problem of excess body heat; the suit needs to dissipate the excess heat from the body, as it insulates the body against the vacuum of space. In real life, space suits are attached with tubes that dissipate the body heat when the astronaut is on a spacewalk; the suit has a cooling system for this. But Kane didn't have tubes to dissipate his body heat with, so where does his body heat go? Why not the helmet?
That's speculation, not really a correction. It's a space suit; that much is clear. It doesn't have a visible cooling system like a real-life space suit, but this series takes place in the distant future. We're getting a little hung up on this one example, but honestly, these films are 40-plus years apart. There are dozens of other instances where it is clear the facehuggers and the xenomorphs can see more than just body heat.
The xenomorphs can definitely see more than just heat, but that's not the statement in the movie. I can think of no examples that show facehuggers can see anything more than just heat/infrared.
Plot hole: In the opening scene, Wade applies to be an Avenger, and does it in the Sacred Timeline, the main MCU timeline, on Earth-616. Not his own, which the movie classifies in the next scene as Earth-10005. Assuming he can just do that (at the end of his second movie he certainly did stranger things than that with Cable's device), one fails to see the purpose of it. Let's assume he aced the interview and got hired; it's not his timeline. He does it to have a good relationship with his girlfriend. Who...is in a different universe. Whatever Wade does in the vastly different universe is not altering anything in his own. It was never going to work.
Suggested correction: He goes back to his universe. Think Thor...or the Guardians or Captain Marvel or whomever isn't Earth based. They "Assemble" then go back to protecting their little corner of the Marvel Universe.
Suggested correction: But it's Deadpool. When does anything he ever does make sense? He wanted to be an Avenger, he went out to be one, no matter what that meant in the literal sense. As long as he can say it, it's enough for him. Even if it is in a different universe/timeline, he can still say he's an Avenger. He is also a rule breaker, so maybe he can figure out how to make it work.
I knew this was going to be the objection to it; it's Deadpool, he can do whatever, etc. There are multiple times during the movie when he mentions things that he is not supposed to know because they are meant to be fourth-wall-breaking jokes. He references real-life actors, he interacted with them in previous movies. So they are absurdities with a purpose, and it's pointless to argue with comedy. But him being rejected by the Avengers is part of his motivations and of the 'serious' part of the plot, which is focused on his own universe and his girlfriend. Earth-616's Avengers though? The namedropping for nerds is an absurd choice when you think about it, which the movie does not want you to do, since it makes zero jokes about it. Without that caption it was not even going to raise any objection or paradox; he could have met with the Avengers of his universe, any universe - later in the movie Wolverine says "F*** the Avengers" as if he knows them.
Two things: 1. Even if he is able to join the Avengers on Earth-616, being part of a team might give him a sense of belonging and change his whole attitude. It wasn't to impress Vanessa about being an Avenger, it was to change his attitude which had soured after the events of the second movie. 2. It cleverly explains that the Marvel characters from the Fox universe were in their own universe and, to this point, have likely not been a part of the MCU.
Maybe his universe doesn't have Avengers and he found out about them through the MCU. That's what I'm saying. It's just a gimmick in the movie and actually doesn't affect the plot that much as he was given a task by the TVA (or whatever lone wolf from the TVA) and teams up with Wolverine. Him trying to be an Avenger and talking about it is just a running gag.
Plot hole: Given contestants were carefully checked for steroids at show time, mainly by urine tests, it seems unlikely Jackie would have been allowed to compete once her steroid use was discovered.
Suggested correction: Not at the amateur level, and not during the time period depicted in the movie.
Plot hole: The movie establishes that the FBI has a list of suspects thanks to security camera footage from the area where the victims were found. "A red headed man, two African Americans above average height, a white haired man." Then, the zinger; "a man in his 30s with a tattoo of a rabbit or an animal on his right arm", which of course is our guy Josh Hartnett. We see the tattoo, and it's a little doodle of a sheep, about a couple square inches big, below his wrist. That doesn't really make sense; if they have security footage with that level of detail, one wonders how could the rest be so vague. The next entry mentions "a male with a scar on his jaw", which is even more absurd. Either the security cameras picked those details up along with the suspect's full appearance and mugshot, or they just can't know with such certainty (if the suspect was masked or concealed in any way, then they would know for sure it was the killer and wouldn't be chasing people with wildly different appearances).
Plot hole: The first scene at Area 51/55 shows Rex Strickland operating an acid 'shower' that will be the key for the movie finale. Venom is not present at this scene but knows exactly how this never-before-mentioned or shown Chekhov acid works and that Strickland is the one guy with the necessary clearance to use it.
