I guess horror is subjective...

Rating: 7/10 (16 March 2014)

....because i really didn't find this movie particularly scary.. It was actually pretty by-the-numbers... The best sequence was ruined because of the trailers showing it (the whole hand clapping bit.)
I liked the cast. Patrick Wilson and Vera Farmiga are 2 actors who i seem to like in everything. And there were SOME neat bits (like when Lili Taylor is covered with the sheet, and then vomits blood on it from the inside) but overall i found the whole thing pretty predictable. Everything that will happen is spelt out for you far in advance.
It was technically well-made, i suppose. James Wan knows how to make a movie LOOK good, but i feel like it was a bit over-hyped as far as 'great horror' goes.
