I didn't laugh at it, but there were a couple parts that seemed a bit ridiculous. Overall it was a pretty dark movie and some scenes truly creeped me out. A lot of people who didn't read the book (including myself) felt the ending was too sudden and confusing. There were times in the movie though where I felt completely immersed and on the edge of my seat, mostly during the first half after it got going. A friend of mine felt he would have rated it a 6.5 on a 1-10 scale, and I'd agree with about that rating overall. So far my favorite movie this year is still Batman Begins
