It's entirely possible that sending the audience out feeling lousy was intentional

It is not only a funny movie, but it allows a great amount of joy for anyone who watches it.

The film makes a home in your brain and the only cure is to see it again.

The movie is made so realistic it has a lot of that WoW feeling at the right moments and never tooo over the top. the suspense is done so well and the emotion is felt. Very well put together with the music and all.
