I expected so much more to be honest. The first half was extremely average.. all the usual horror. And that policeman couldn't be more stupid if he tried. But towards the end it does ramp up a little with some quite comical bits. I especially liked the scene of the ceremony by the "hellhole " The actual ending does seem a bit rushed and there could have been a lot more destruction. Not terrible but I really don't understand so many high reviews. There are so many much better creepy movies out there. A great one is The Name of the Rose. Not supernatural but very creepy and absolutely excellent.
