The bonk on the head to incapacitate. It always works instantly and has no long term implications.

This:

Characters in dystopian settings with clean faces with makeup, and perfectly coiffed hair. You're telling me that whoever built your doomsday vault decided that a 10 year supply of concealer, mascara, lipstick, etc should be part of a survival kit?

This one is a bit more specific, but in the new dune movie, literally everyone just starts panting and heavily breathing through their mouth after any exhertion.

The fremen absolutely know better, and I'm almost positive there was a line in the first movie when they were explaining desert survival to Paul where they say you must preserve as much moisture as you possibly can so always breathe through the still suit

It’s an old trope, but still bugs me: Ordering food and leaving the table long before it could have arrived.

If you wanted to have a 5 second conversation, meet under a lamppost or something, not at a fucking diner!

Characters not saying "bye" before hanging up the phone.

Star Wars Episode 8 is the one that lives in my head ever since it was released.

Play by play of the opening sequence battle:

First Order ambushes the Resistance base as it is evacuating

First Order summons a ship described as a "Fleet Destroyer".

First Order only has enough time to charge one shot, but has 2 targets: The Resistance base full of intel and equipment that can't move or the Escape Fleet with all the escape ships and evacuated people.

So, who do they shoot?

The base full of intel on the ground...

Generally speaking: Things that humans would never survive. Like, if someone is thrown so hard against a wall that they go through it, they're not going to live (this happens with non-super characters). Or when someone is falling from a great height and they grab hold of something to catch themselves. Yeah... No.

Or in scenes where fire is present... People having a discussion without coughing their brains out, being able to see, and easily keeping their eyes open, just a few feet from raging flames.

After experiencing any and all of these things the characters will just continue in the story and be able to move and breathe like nothing happened. Sometimes they'll move with a limp or cough occasionally but this is usually right before they make a 100m dash in record time.

My specific example is The Butterfly Effect when he gives himself stigmata in prison; the movie has already established that's not how it works. Looper made a similar mistake, again not following the rules the movie itself set up.

The more general example: sprinkler systems. Basically every single time a sprinkler system goes off in movies and TV it's wrong. They get it wrong so consistently that it's trope at this point and would confuse people if they decided to get it right.

Each sprinkler head is triggered by heat individually, so smoke won't make the place get flooded out, and holding your lighter up to the head will only make that one head go off. The systems would be so poorly designed to work like in the movies, with false-triggers and flooding areas nowhere near the fire all the time causing more damage than fires.

POV when using binoculars has two circles, which isn't how it looks when you actually use them. It should be one circle.

Camera footage that's played back in movies as part of the plot always has the recording icon, time code, etc burnt into the footage, which should really only be visible on the camera monitor while recording, not during playback and especially not on another device.

Kidnappers always FaceTime the victims family. No one uses Android? They can't take a few minutes to download Google Meet?

Nobody ever says "bye" in phone calls, the conversations just abruptly end and one side closes the call when they've heard enough.

These are more common in tv than film but happen in both:

Any time a shot is given with a syringe, especially by an addict, it's almost always done in a way that would severely damage the person.

And more of a narrative issue that is common, but I hate the trope where a person overhears part of a conversation and jumps to conclusions, but had they listened for a few seconds longer it would have contradicted their conclusions.

Empty cups

Everything about every time travel movie ever

Any time the villain has the upper hand and then leaves the room with no reason not to just kill the protagonists.

Don't get me wrong, I'm not hoping for the good guys to catch a bullet to the face. It's just that it's lazy writing. Give them a reason to be left alive, or create some distraction that requires attention. Not just "I want you to see this" sort of bullshit, but a legitimate reason.

Alien: Covenant

For all the hate this movies catches, I've never heard a complaint about the opening. The run into a neutrino burst.

"Why do you guys even have sensors for that?! Pretty neat!"

And it wrecks the ship. Because fuck you, that's why.

People randomly being able to increase their bandwidth. It's less so now (and happens less) but jfc seeing plot points in the oughts where something like an adsl connection was instantly beefed to 'moar bandwidth' on the fly with no one dealing with any of the infrastructure that physically rate limited (especially at the exchange) makes me graaar

Noises in space. I know Star Wars is the worst offender, and people have tried to make excuses about how ships have speakers that add explosions and laser noises, but that's crap.

In The Dark Knight it's bothered me that two-face didn't develop any pronunciation problems after losing a cheak and half a pair of lips. I know, I know, it's a comic book movie, but seeing him pronounce the 'b' sound with his teeth showing takes me out of it every time
