Maybe it's just me but there are a number of things characters seem to do in movies that are really irritating.
For example:
They walk into homes and leave doors wide open behind them.
They hang up the telephone without saying "bye".
They order drinks, take one sip, then leave.
They don't unclasp necklaces, they pull them off breaking them in the process. (then sometimes immediately put them on as though the clasp is still intact)
They throw away expensive firearms just because they've run out of ammo.
They pour gasoline on the ground then toss in a perfectly good Zippo lighter.
There are many more but what do you think?
Any that spring to mind that you find annoying?
Or is it really just me?

Edit: Annoying movie clichés or repetitive storylines are also welcome, but please, if you reference a movie directly, try to include a spoiler warning if it needs one.
My heartfelt thanks to all who have commented, it's been great fun!

Was it the "dickhead" comment you found offensive?
Or am I just not allowed to reply to trolls in general?

Please read all the comments Brad, the "army" slant was theirs, not mine!

everyone is gonna have complaints about movies. this is just where we voice ours. Everyone has diffrent things for example I can't stand Quintin Tarentino. I hate him and any movie he has ever made. He just bothers me and I dont like the way he directs. now I would never tell someone not to like him cause if you do you do. No reason for anyone to get "upset" Not everyone will be like you in fact everyone is different from you

not so much a peeve, but when the guy in the shot is clearly hotter than the chick so you find yourself staring at him instead and rationalize that this does not make you gay and that the chick is just really ugly

I hate it when you see the trailer for a movie and it looks really good, then you watch it and find out the bits in the trailer were the only good parts throughout the whole film.

Plus any trailer that reveals the whole plot annoys the hell out of me, eg. Terminator Salvation.

I'm with you on this, but what about when the only good bits were in the trailer, but they weren't even in the movie?
I can't think of an example off the top of my head, but I do remember that there were movies that people went to because of the trailers and were disappointed because those scenes were missing.

I already tried that, during a paintball game, and believe me, the cinema is far from reality. These suckers shot me right in the only unprotected part of my body

Yeh i don't know how they can get away with it, isn't it basically false advertising?
Paranormal Activity 3 got quite a backlash for that, there were about 4 scenes showed in various trailers that never made the final cut.

you know how it used to be the token black guy and nowadays its the token indian guy? hate that
