Oh good lord. Raging Bull is not only exemplary as a textbook highwater mark of method acting, it is also a marvel of cinematic ingenuity. The exaggerated and expersionistic sound effects, the alternating styles in every fight, and just the absolute disintigration of the one time great. I've seen it three times at least and think it a masterpiece and quite possibly Scorsese's best (which is saying a lot considering my near obsession with his work). De Niro alone is worth sitting through ALL of the movie. It does help if you're into boxing as well.
