Sometimes a movie gets so built up it is hard for it to live up to expectations. I saw Million Dollar Baby and The Aviator both were very good, but didn't exceed expectations. I think this is more because of the nature of how movies are pushed.
I agree though I didn't find it to be glorifying euthanasia.
I'm serious. If you want to see a movie that will exceed all expectations then go see "Finding Neverland". It was just incredible.
