Re: Incredible Hulk 2
^ See, I felt like TIH was in line with this. I know Leterrier referred to it as a "monster movie" in some interviews, and NortonHulk had a line like "I don't want to control it, I want to get rid of it."
The problem Marvel has, or at least they feel like its a problem, is that they want the Hulk of the MCU to be a hero first. Feige has said this in some interviews.
Like you, I also don't love that Banner has control, and wouldn't mind if Hulk goes rogue and strays from the team. Maybe it can be a plot point in a future Hulk film. Maybe the Leader experiments on him further or something like that, i don't know... (hopefully the people who get a paycheck for being creative can think of something better.)
