It's an 86-hour movie. Not every minute of it is absolutely perfect, but most of them are. Nothing else even comes close. Nothing else creates such a universe. Tony/Gandolfini; there's never been a better role and performance in anything, ever. He nearly steals the movie with his three minutes onscreen in True Romance. Sopranos gives us, what, 40-odd hours of that? It's untouchable.
Michael/Pacino in Godfather/II is also a great role and performance. 6 hours total, and he's onscreen like a 1/3 of the time? So 2 hours? Even on a minute by minute basis Tony beats Michael, let alone when viewed as a whole.
Peep Show is the only thing that comes close. Mark and Tony are neck and neck for the best character, ever, in all of recorded media.
