I honestly think if this was a few years ago and they were casting Incredible Hulk, we would all have been really surprised and thrilled to get Mark Ruffalo. He is a really good actor and I completely buy the casting. Some of us are just upset because we loved Norton (or Bana). It does suck that over the spam of 10 years and 3 movies, we will have 3 different actors as Bruce Banner, but it could be a lot worse, I guess. I am just happy that they went with an actor, and not a name. I just think back to when WB wanted Ashton Kutcher for Batman because he was the "it" guy at the time, but Christopher Nolan comes in like "yeah, about that, I got this Bale guy... people seem to like him."
