Stupidity: In the Anubis universe, immediately around the time Lawless says, "Something's wrong," if you look closely, by Lawless, you see the two police officers behind Jet Li walk away to leave Lawless completely unprotected from behind. I understand it's a parallel universe, but that's some really bad police work to leave a prisoner wide open like they do.
Stupidity: The creatures in the maze make it inside the living area after the gates open and some of the heroes hide in the corn field. While that alone isn't the smartest thing... one of them keeps a lit torch in their hand burning brightly at night while trying to hide from these creatures.
Stupidity: Amongst the dubious statistics attributed to the real Frank Dux at the end of the film is the claim that he holds the record for "Most Consecutive Knockouts in a Single Tournament - 56." A single tournament with at least 56 rounds would include over 72,000,000,000,000,000 entrants.
Suggested correction: While the entire film could be considered fiction based on Dux's dubious claims, your statement is only valid for a single-elimination style tournament. There are other types of tournaments, such as a round robin which would only require 57 contestant (Dux plus at least 56 guys to knock out).
The kumite is a single elimination tournament. It wouldn't make any sense to have a full-contact tournament, where the action is so (legally) violent that fights routinely end in severe injury or even death, use any other form of bracket.
Nothing is stated that every tournament Dux was in was the Kumite as depicted in the film. Just that he retired undefeated in the Kumite.
The records listed at the end of the film are kumite records. The information comes from Frank Dux himself who made the claims on more than one occasion. When it says 56 consecutive knockouts, it is referring to the kumite and not some other, possibly round robin (which honestly would still be a ridiculous claim) tournament. It is likely the makers of the film believed "consecutive knockouts" meant "single tournament."
I guess everything I've read on him over the decades never made it clear it was talking about one type of tournament with all the accomplishments he's claimed to have. And I've read the same repeated factoid about how many contestants 56 rounds would have that you read.
Stupidity: Catherine, wearing a dress and coat, was outside in the snow chopping firewood while her teenaged son sat nearby playing video games on his tablet. This could also fall under "plot hole" because having the son close by made him available to try to help his mom when Pryce attacked her (with the intent to rape). (00:36:40 - 00:37:15)
Stupidity: The metro police officer (and co-conspirator) went to the old cement factory where the other bank robbers were. Since the police officer (accomplice) wanted the money and did not want other police officers to be nearby, he called 911 and made an anonymous false report stating he spotted the person police were looking for and misdirected them further away. Maybe a good idea, but he made this call using his own cell phone. (01:12:20)
Stupidity: Just after Ricky has beaten up Tarzan, the warden has the ceiling of the cell Ricky is trapped in lowered in an attempt to crush him. However, earlier in the scene, Tarzan made a huge hole in the wall of the cell to get into it. The hole in the wall is even visible in the background when the ceiling begins to lower. Ricky could have simply run out of the hole in the wall to get out, rather than try to hold the ceiling up with his bare hands. (01:02:48)
Stupidity: Spoiler alert. After the son makes it out, he could get a rescue team to get his dad by going in where he came out.
Stupidity: The bad guy who spies on Bosley is visible from the very beginning of the scene, when Elena is not even inside the cafe yet. The cafe does not have many customers and the bad guy is using a loud vintage typewriter with a big mirror mounted on top (!). The Angels are portrayed as being super smart and their setup is so careful, but somehow they managed to miss something amazingly obvious. Conversely, nobody would have ever paid attention to a laptop or any silent, modern-age device perhaps with a camera or something similar, so the bad guy chose the most blatantly conspicuous accoutrement for his spying job. Try showing up to a cafe punching the keys of a big clunky typewriter and literally everyone will be looking at you. (00:18:25)
Stupidity: During the battle on the harvester, Chani is firing an anti-aircraft projectile at a Sardaukar approaching her. Although the projectile is strong enough to destroy an ornithopter, instead of blasting the Sardaukar away, it pushes it into the air until it hits the harvester track. (00:36:39)
Stupidity: The team raids the house and locates 5 people inside deemed to be Russian operatives. They are subdued and placed on their knees, while some of the team works on gathering intel from the home. The subjects should have been handcuffed/zip-tied. Since they were not they were able to grab stashed weapons and cause a gun fight which led to one of the entry team's members being killed and all the Russian operatives killed. It's common knowledge to restrain people. Cops and military always restrain. (00:04:00 - 00:12:00)
Stupidity: Mar-Vell's laboratory is a spaceship that the captions identify as an imperial cruiser, not exactly the kind of thing that can go missing unnoticed. Since the Kree were so determined in finding Mar-Vell's work and are so attached to it that they keep Carol around, how is it possible that in 1989 or ever since they haven't looked for her cruiser? Carol manages to uncloak it without using any secret code (that she wouldn't know since Mar-Vell told her about the whole alien thing just barely before dying and was not privy to any security measure).
Suggested correction: Decloaking the ship still necessitated knowing its location. The Kree didn't know where it was, so couldn't decloak it.
But they don't even look for it. He literally goes "oh, well, the engine is gone, let's go home", without any attempt to look for Mar-Vell's project or, again, the big cruiser thingy. Something so important, and yet the empire does not care about it to probe around for it.
In your other entry you suggest Ronan doesn't even know about Mar-Vell's project. More likely he doesn't care, since he is a fanatic who worships the old ways. Its logical he will ignore it, especially when his interests have been turned towards Carol flying around blasting through his ships. Which he later forgets for whatever reason as well.
No, no, I am referring to Yon-Rogg in the past, and the empire as a whole: they are after whatever work Mar-Vell was doing, to the point of keeping around with a very flawed brainwashing plan an incredibly dangerous being created with that technology, but don't look for her ship or evidence of her work, at all. 6 years with the knowledge that somewhere around (or on) Earth there's the key to unlimited destroying power and/or a hyperfast engine, and everyone is like "Meh, whatever" for no reason.
Stupidity: Very soon after Damon is stranded, one of the many satellites around Mars inevitably picks up the fact that he has moved various objects around his site, indicating that he's still alive. Yet it never occurs to him that this would obviously, eventually happen. In which case, his best option would be to simply spell out a message with debris and stay put instead of planning some 50-day journey.
Stupidity: They have the technology to track the movement of the rebel troops, and while the Nigerian airspace is too hot for extract, the fighter jets landing behind Tom Skeritt on the carrier could easily wipe out 300 rebel soldiers.
Stupidity: Kora and Gunnar arrive at the town to find the rebel Bloodaxes via a contact of Gunnar's. They literally see this contact being hauled out of a bar by bounty hunters who work for the Imperium...and then walk straight into the same bar and start openly talking about needing to find the rebels right in front of the bartender and other patrons, who for all they know are all Imperium-aligned.
Stupidity: Why in the world would Tony of all people leave his old suits in storage WITH the miniature arc reactor still inside the suit? This would have served no purpose to Tony since he already has his own arc reactor in his body.
Suggested correction: This is a question which is easily answered; Tony had the idea of putting someone else in the suit (like Rhodey) himself. Plus, it's logical to think he has built multiple miniature arc reactors, after the events of the previous movie. Plus, he can probably just as easily switch from arc reactor to arc reactor in his chest when changing suits, so he has a fully powered arc reactor ready in each suit.
