I LOVE this movie! I caught it on TV one night, not knowing a thing about it, I watched the entire thing and absolutely loved it, then bought it. It's super dark and eerie and it does have its scary moments throughout. Played exquisitely by both Katherine and Emily, the effects are great and the story is awesome for a horror. The violence is extreme, very gory and the language is very strong. The one 'sort of' sex scene shows nothing..just a bit of making out prior to it. Overall, this movie rocks for any hardcore horror fan! See it!
