The Godfather is No. 1 for me. Over the years, Donnie Brasco has really grown on me. Donnie's character, like Michael in GF1, is genuinely conflicted and that holds my interest to the end. GF2, Casino, and Goodfellas are all excellent films, but I can turn them off a lot easier because the appeal is mostly plot.
