My father had read the book on which this movie is based, and he literally WOULD NOT SHUT UP about how great the story was...so when he came up to visit for the Holidays, we went as a family to go see it...
Save your money. The movie was HORRID. It was essentially two hours of torture porn, with very little put into the characters (especially "The Bird") to give you the context of why any of it mattered!
Do yourself a BIG favor and just go read the book. Everyone who has says it's one of the most inspirational stories they ever read. Even my father, who NEVER admits making a mistake, admitted that it was a terrible movie and he should have picked a different one for us all to enjoy.
