The Dark Knight trilogy really wanted to be a realistic, grounded take on the Batman mythos, so they dropped the more fantastical elements of some characters' backstories. Ra's Al Ghul was no longer immortal, Bane didn't have super steroids, the Joker wasn't permanently bleached by chemicals...then there's Two-Face.

I guess they thought acid burns were too unrealistic, so they gave him regular burns...apparently without knowing that burns that severe would be so painful that he wouldn't even be able to remain conscious, much less run around the city on a killing spree. I mean, you can see exposed muscle in some places. There's a line where Gordon says he's rejecting skin grafts, and I remember thinking, "WTF are you talking about? He should be in a medically induced coma, not making healthcare decisions." Half of his body was an open wound; I'm amazed he didn't die of infection 15 minutes after he left the hospital.

First time I saw the Jurassic park I thought no way would intelligent people just run around a huge and therefore dangerous Brachiosaurus or jump out of the car and run right to the ill Triceratops. That would be Darwin's award kind of madness.

Then I studied biology, got to know some zoologists and paleontologists, and yeah, this is exactly what would happen.

Space Flight.

I walked in on my roommate watching "Don't Look Up" right during the space shuttle launch scene. Literally every single thing was wrong. The trajectory the shuttle took off the launch pad. It flying RIGHT SIDE UP as it did the gravity turn like a fucking airplane. The fact 50 other rockets were in formation with it despite that being stupidly dangerous, them all having different TWR ratios, there not being nearly enough launchpads anywhere in the world to do that, etc. Just everything.

We have existing video footage of shuttle launches. It's not some crazy mystery. This isn't Gravity where they add a window that doesn't exist on the ISS for dramatic tension. It's not Star Wars where the X-Wings behave more like airplanes than spacecraft for visual appeal. This was deliberate negligence.

A very common one is spacecraft seem to always launch in a direct line away from the planet. They just go straight up. That's the least efficient way to get into space. But I usually let it slide because explaining orbital mechanics and Hoffman transfers isn't necessary for good story telling.

Where in countless mystery/thriller stories bad guys arrange meets in huge open deserted buildings, to be uninterrupted. In the real world, the place will securely locked and gated, or multiple houseless people will have already moved in there.

We just watched "The Trap" last night. There was a major pop concert that ended in time for family dinner time during daylight. In the concert, they were depicted having time to make multiple trips to the merch tables and concessions, and in one of those trips, they talked like it was an intermission to change the stage set between songs.

When someone’s falling hundreds of feet and when they’re inches from the ground a super hero swoops in from the side to grab them.

Sure, they didn’t hit the ground but not only did you catching them slow down their vertical velocity just as fast as the ground would have, now you’ve accelerated them horizontally so fast that they’re now twice as dead as they would’ve been otherwise

Kingsman

Training scene where they shove a shower hose down a toilet and use it to breathe...

There would be no air (or even sewer gas) to breath in that case. Toilets work by raising the water level in the bowl above the water level in the S-bend/siphon. Since the room was full of water, those toilets would have been flushing constantly, and the whole pipe would be full of water.

Better(ish) solution. Use the body bags that they each had to fill out and place in their trunk/locker to capture an air bubble. That would at least give you some time to attack the door, or figure out how to drain the room.

There’s a scene in Spider-Man: No Way Home where Tom Holland is fighting the Green Goblin. Goblin grabs Spidey, jumps with him, and then they both smash through the 23rd or so floor of the apartment building they’re in and they land on the floor below.

Sure, they’re both super strong but neither of them used their strength to push through the floor. They just jumped and reached no more than like a foot off the floor, implying that gravity pulled them both through the floor. Okay, so the floor was built poorly, but then why did falling 10+ feet from the 23rd floor to the 22nd floor not make them smash through the 22nd floor?

That movie’s a lot of a fun but that scene makes me upset lol

I think a good common one is explosions that throw people at least 10 feet without killing them. If the shockwave is strong enough to do that, isn’t it strong enough to tenderize and completely disable all of your internal organs as well?
