Stupidity: David and his partner Cal drive into a weeded area near the garage/warehouse the drug bust is going to be made. David says, "This might go south. We need backup." David and Cal sit in the car talking about not letting the product get onto the street where someone might die, etc. then exit the vehicle without calling for backup, which could have been done in a few seconds (and should have been done as soon as David said they needed backup). (00:02:10 - 00:02:37)

Stupidity: Drake's bike fell over on the sidewalk perpendicular to the parked RV, not far from the middle door. It would've been hard for someone to miss seeing the bike when near or in the RV. When Steve went to get his dog Bentley, Drake's mom drove up and asked if he'd seen her son who was riding a bike but didn't come home last night. Steve didn't bother telling Drake's mom he was going on vacation, but said he'll "keep an eye out." Steve still didn't see the bike on his way back to the RV. (00:04:30 - 00:07:00)

Stupidity: The location of the small hole near the bottom of the wood-trimmed wall where Everette passed Sharyn a note and pencil would have taken much more time and effort to accomplish compared to merely penetrating the wall a little higher (where there would not have been wood trimming/baseboard on both sides). (00:10:00)

Stupidity: Rick tries to kill Frank at his boathouse by dumping gasoline all over the place and using Ray Coleman's lighter that Frank had. At this point, Rick has gasoline over his arm, but instead of properly cleaning it, he opens the lighter immediately and has his arm burned. Surely a criminal genius like Rick wouldn't have risked this as this is a loose end. Further mention goes to when he has the bathroom door open for no reason while medicating the burn mark, which enables his wife to see him and discover who he really is.

Stupidity: When the Woolworth Building collapses and the gang runs into the convenience store to take cover from the dust, Marlena was last seen behind Hud and with Lily, Rob, and Jason. Switch to everyone running from the dust cloud, Marlena didn't make it into the store. Upon exiting the store, the gang finds Marlena stumbling from nearer to the Woolworth Building meaning she would have had to run toward the dust cloud, through the screaming crowd which was running away from the building.

Stupidity: The secret service officer near the elevator gets shot right in the middle of his head by the Penguin mascot, and she drags his dead body into the elevator. Suddenly he's able to moan and groan and she shoots him again. The guy was very shot in the head, as in graphically. How is he suddenly alive enough to moan?
Suggested correction: A bullet to the head is not guaranteed to kill someone. Movies and video games have taught us that being shot in the head is instant death, but that just isn't the case.
Pretty sure you wouldn't wake up in seconds after a bullet to the head.
Correct. You probably would just lay there stunned while moaning and groaning... exactly like the scene depicts.
He didn't "wake up", he moaned. Which is 100% possible and actually happens quite frequently.
Someone I know shot himself in the head. He was making sounds when found and "lived" for another three months, though there was no higher brain function anymore.

Stupidity: At the end Vince fires a grappling hook at the passenger seat of the truck then attaches the other end to himself, all the truck driver has to do now is hit the brakes and Vince would be dead under the truck or dragged along the road.
Suggested correction: In point of fact, the truck driver does slam on his brakes; but, defying physics, Vince is catapulted around the right side of the truck to the passenger door.

Stupidity: At the end, the police inspector talks Bruce Lee into surrendering, and about 8 people (including the inspector) escort him out of the school. As soon as they're outside, Bruce sees a formation of heavily-armed police preparing to fire. Realizing he was betrayed, Bruce Lee charges, screaming, straight into a barrage of gunfire as the action freezes for credits. However, before the action freezes, there's NO reaction from anyone standing behind Bruce Lee, even though they are directly in the line of fire. Even the police inspector (who knew the police gunmen were waiting outside) just stands there instead of immediately diving for cover.

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: If the ninja can inhabit a dead body (and one that has been dead for a LONG time, even) without any penalty in his agility and powers and it is stated that only another ninja can truly kill him (which surely seems correct, since he would still fight even when hit by hundreds of bullets), the whole movie plot that involves him possessing Christie - who is a reluctant and part-time host - does not quite make sense.

Stupidity: Despite being assaulted by an intruder that she managed to temporarily fend off, the female neighbor takes forever to say something when she calls the police, which is just enough time for the villain to regain his senses and attack her with a huge drill.

Stupidity: Becky possessed the mysterious key that the four neo-Nazi prison escapees were at the lake house to retrieve. Becky didn't know what the key was for, so did not have a vested interest in it. By first denying that she knew where the key was and later refusing to give it to Dominick, her father was killed. Had Becky simply handed over the key when Dominick asked for it, it is possible no-one would have been hurt/ killed. Becky keeping the key with no importance to her served to further the plot.

Stupidity: After eating the bird, why didn't Becky send her phone down inside the bird, but instead climbed down to put her phone inside Hunter's body?

Stupidity: Noah loves the classics, he shows passion and interest in them, it's part of what wins over professor Jennifer Lopez. Witness this risible exchange, about Achilles; "He killed this guy, Hector. But instead of hiding out like a pussy, he..." "Dragged his dead body around for everybody to see." "Yes." The sheer dumbness of this exchange, especially the first statement, hurts the brain; why would a warrior 'hide out like a pussy' for killing an enemy during war?
Suggested correction: Achilles killed Hector in an act of revenge, not an act of war. Hector was a beloved warrior and treating his corpse with disrespect could have insulted the Trojans. Knowing this, Achilles dragged Hector's body around the city in an act of boldness. So yes, instead of "hiding out" after killing his enemy, Achilles acted like a "badass", taunting the Trojans with his victory over their champion, disregarding any threat of reprisal. There's nothing stupid about this exchange.
"Dude, there's this book about a Greek war with gods and heroes and sh*t: you know what, the main character kills his enemy in battle and doesn't hide out after! Like it's a war or something." What a stellar and perfectly not stupid pitch about the book! Makes totally sense and it obviously woos the college professor too! Mind you, I don't want to come across as sarcastic and I enjoy reading your comment, but the "not an act of war" objection is irrelevant when all the action happens in the battlefield, regardless of character motivations. Point is, the statement does not follow logic when it comes to pitching an epic fantasy book to a young adult, and on top of that, this fundamentally flawed series of statements is even painted as something totally impressing a college professor.Surely my flawed perspective of a snob living amongst snobs in a country where the study of classics is more widespread than the US, but blurting out something like that would get you a giggle at best.
I think you're putting too much weight on the "not hiding out" part of Noah's statement and not enough weight on the defiance of Achilles, which is what Noah was saying he was impressed with. For this to be a stupid statement, it would have to be incorrect. It isn't incorrect. Noah describes exactly what happened. Sure, he uses a colloquial tone but all he's really saying is "Achilles kills Hector in a duel and rather than flee the battlefield afterwards, he parades Hector's corpse around the city to intimidate his enemies." You seem to be hung up on the "fleeing the battlefield" part, as if that is a reading of Achilles actions that is so off base it rises to the level of a mistake in the movie. I don't believe that to be the case. Also, this college professor is impressed by the fact a youth would read Homer on his own at all, and the fact that he's incredibly charming and handsome certainly doesn't hurt.
I put weight on it because it sticks out: the line itself is designed to get attention using that colorful expression. Even as you paraphrased it with "Achilles kills Hector in a duel and rather than flee the battlefield afterwards" etc, the problem is not the tone: since when it's the go-to move in the genre, killing someone in a duel and then fleeing? I can't see why this would be a logical thing to say, so strongly even, to pitch the book to his friend! Like pitching a restaurant prefacing unironically that they do not spit in your food. His reading is not technically incorrect, or I would have put it in the 'character mistake' category, but mentioning what did (not) happen is daft and contrived. And yes, it is a dialogue that is supposed to reinforce that 'incredibly charming' quality you mention but it is written in such a childish way that undermines it, also considering that he told her he already studied Homer in his previous school and he is not exactly a kid.
