Hahah! It’s so cliche. #-O
Now they’re doing it so that they *think* it’s disarmed, and then it starts again for some reason. I think writers/directors are getting wise to this crap and not doing that scenario as much.
But then think about it. If it’s not a bomb, it’s something else that gets accomplished at the very last second (a jump, a bullet, a flying manuever). Funny ain’t it?
