DDL may be the technically better actor, but I gotta give it to my man Al. He's had great performances in some of the greatest movies ever. I love him as Michael Corleone because you see a man turn to stone right in front of your eyes. Honestly, this is a close one that could go either way, both guys deserve it.
Still...."vastly under appreciated third installment"? WTF Godfather 3 was a terrible movie, and Als performance had nothing to do with his performance in the first 2. He was already in that Pacino caricature, yelling all the time mode. I gave it to Al cause Im drawing off the highs and not using the lows to affect the scores, or else he would lose big time due to being in crap movies like part 3 or Gigli
