Note to movie studios: stop putting stuff like that in movies. It's not suspenseful, it's not dramatic, it's just idiotic. We KNOW the hero's going to make it out fine. Stop having him cut the wire at the last second (unless he cuts the wrong wire and the bomb explodes - that would be awesome to see for once).
Some others that I hate have already been posted, like when the hero runs as fast as he can while the bad guys fire bullets and he doesn't get hit once. Also, I hate it when the hero's being shot at by the bad guys and he runs without getting hit by the bullets (as I just said) and then he jumps through a glass window or whatever and lands on the other side, miraculously unscratched. And I hate basically anything that's way too unrealistic just to seem dramatic. I mean, I don't have a problem with unrealism with movies (I'm a Star Wars fan, aren't I?) but sometimes they sacrifice so much realism just to make something seem more dramatic or suspenseful (those two examples I mentioned) that it just becomes ridiculous and unoriginal. Why can't the bad guys shoot at the hero and have the hero get hit by the bullets and fall down and die and have the bad guys win? Or how about the hero jumping through a glass pane only to find out that glass isn't quite as conveniently smooth as he'd hoped? Those would be really cool and original to see, instead of always being so boring and predictable.
Well, to sum it up, I basically hate any movie cliche that involves the hero miraculously getting out alive and completely unscratched and having a perfect, happy ending.
I'm sure there are others I hate, but I can't think of them right now. I'll post them when I remember them.
