*SPOILER?* Is this the movie that ends like...?
I'm trying to recall a movie I once saw the ending of, and I swear it was this movie. But maybe I'm wrong. The movie I saw ended like this:
A group of kids/teenagers are in a house/cabin with a pair of adults (their parents?), and suddenly the lights go out and this figure in all black appears. This guy can throw people through the air, pin them to the walls, create giant iron-cast orbs, and possibly shoot lightning from his hands. And the way he's defeated is by being sucked into some kind of vacuum cleaner.
Is that this movie? If not, does anyone know which movie it is?
