Shit I'm tired of
In a TV show or movie, when someone is standing or walking in the street and is suddenly hit by a car, or even better, a bus which comes seemingly out of nowhere. Most recently I've seen this on the new Terminator series...twice in two episodes. And just off the top of my head I remember pretty much the same thing from Final Destination, Lost, Daybreak, and The Black Donnelys. I guess the reason writers like this kind of thing is that it's so sudden and unexpected for the viewer. The flaw, however, is that the person who is hit by the bus should be able to see all that stuff that is off camera for the viewer.
This also extends to the person driving a car, with the camera looking at them from the passenger seat, when they're suddenly blindsided by a car slamming into the driver's side door which also seems to be quite popular these days.
