Example of its over-the-topness:
There's a scene where a couple are having sex in the bathroom stall on the plane. They tear the smoke detector out of the ceiling so they can smoke pot. A snake or two fall through the hole in the ceiling and start biting the hell out of the couple. One of the snakes bites the girl right on the tit and hooks on. Then it cuts to the next scene.
I mean, c'mon, this movie even has Snake-vision!
