Drag Me To Hell is a movie in which a young woman is cursed by a gypsy. The curse will drag her to hell. She wants to stop the curse. That's all you need to know.
I noticed that I've been highlighting a lot of horror-comedies this year. Maybe just the kind of mood I've been in. I really like Drag Me to Hell. It has some CG effects, but they didn't feel as overused as they did in the first episode of Ash Vs. The Evil Dead and it also has some really gross scenes that make me laugh.
My daughter refuses to watch this movie because she was so grossed out by the gypsy woman vomiting all over the protagonist. If that kind of stuff bothers you, I would suggest staying away from Drag Me to Hell.
I think it's a lot of fun and if you go into it just knowing it's by the creator of Evil Dead, you'll be fine. I don't think he gets enough credit for this movie.
