I don't know how this movies got that many bad reviews, but it's a bit undeserved I think. I kept thinking they'd do things other movies do with horror...you know...overkill. But they didn't. It was actually pretty decent. One of the things I loved was the fact that they actually killed the thing in the end...and she stayed dead - not the usual '3 years later'...and it comes back again. And drowning - a perfectly reasonable way for a demon to go! Rotten tomatoes' "top critics" got this one wrong guys.
