I needed to watch 'Raging Bull' three times before I "got" it. The third time I cried. (OK, not streaming tears, but my eyes did well up.)

Jake LaMotta is not a likable character. In fact he's despicable. The story is about how this awful man had everything he could possibly want out of life and because he was such a prick he lost it all. The worst part is in the end he realizes it all. It's really an amazing movie.
