Re: The Joker (The Dark Knight) vs. Bane (TDKR)
I would say McKellan's Magneto surpasses Bane. As does Molina's Doc Ock. But yes, no other Marvel villain really has, including all those made by Marvel themselves. But that is because Marvel is trying to be so family friendly, they do not want their villains to be really nasty. Though that might change with the second Avengers if it really features whatever-his-name-is from the end credits.
But while I prefer Marvel comics as a whole, there is nothing in their pantheon that matches the Joker. So, when someone like Ledger realizes that character so brilliantly, it just is not comparable.
