If you're seriously considering watching this 2:38 monstrosity, then, please rethink. Carol and I would have walked out an hour in, except that we were trapped in the middle of the theater (with at least one immediately-adjacent theater goer asleep) and were trading looks of disbelief because we couldn't figure out why this was so critically acclaimed.
If you must know, the Daniel Day Lewis performance was extremely good, as were the performances of the main characters playing the various youngin's. However, the theme of the film was basically a nihilists wet dream. Complete with discordant (or is that dis-chordant) music.
You probably just want to stay clear.
