Can be anything, from characters not using objects they have on them, to physics not being realistic, or a very big plot hole.
As an example, one of my friends told me that his pet peeve is that in a lot of sci-fi movies, when spaceships run out of fuel, they stop moving, while inertia and lack of atmosphere should keep them in motion.
The bonk on the head to incapacitate. It always works instantly and has no long term implications.

And then the Indonesians become the headrest: https://youtu.be/ErrRhXItBWc?t=1m44s
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 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?
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…
Oh man, the Disney Star Wars Trilogy is full of these.
I get that Star Wars movies are effectively a fantasy adventure series in Sci-Fi clothing, I’m not expecting perfect logical sense out of everything, but internal consistency has absolutely not been Disney Wars’s strong suit.
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.
The water in those sprinklers is disgusting too! It’s been sitting, stagnant in that pipe for years. It won’t be clear water like from the tap and it will stink.
I don’t know about residential sprinklers, but industrial ones will trigger a cascade of sprinklers to flood. The first one drops the pressure on the line, which activates the high volume pump, which will cause all sprinklers heads to open.
Characters not saying “bye” before hanging up the phone.
Or not telling where they are, but somehow the other person knows exactly where to drive.
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.
old VHS cam-corders did burn some of that info onto the tape.
Yeah, but it’s almost never a VHS camera in the movies, and now often a smartphone video.
Nobody ever says “bye” in phone calls, the conversations just abruptly end and one side closes the call when they’ve heard enough.
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.
Everything about every time travel movie ever
Even that one from 2250?
No, no, that one will have been good
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
