Samuel Jackson isn't my favorite actor either, but I think there are certain roles, like Nick Fury (from my limited understanding), where his propensity for being slightly over the top/seventies' pimp is just a perfect mesh. Like I can't imagine his role in "Pulp Fiction" played by anyone else, but I can see other people in the Travolta role.

Iron Man 2 should rock. Except for Gwyneth Paltrow *eyeroll* It's not that I haven't liked her in certain roles, but I feel like Pepper Pots should be strong and she just plays her too weakly.
