Hulk not suck.
Three movies later, they get the big, green guy right. Yay.
Mark Ruffalo does a great job playing a man with a love/hate relationship with the monster that he really is. The anger is palpable in both Banner and the Hulk. His rage defines his actions, both as Banner (trying to hold it back or deny it) and as the Hulk (relentless smashing of friend or foe). Also, I liked the allusion that the Hulk wants to keep Banner around, possibly for a greater purpose. Cool.
