All of them except the ending of course as I haven't seen it yet.
The ending isn't bad exactly, just a tad underwhelming. It happens so often with horror movies - the movie, in a manner of speaking, writes checks that the ending can't cash, and there's a measure of that here. Also like many horror movies it tries to be cryptic/artsy, which is cool for some and maddening to others. All in all, a YMMV kind of thing.
