The fact we aren't getting a solo Hulk movie is crazy. Dude basically saved the universe. His arc has been crazy, and the craziest thing about it is that most of it happens off-screen (him arriving on Sakur (or whatever the heck that planet is) and getting picked to be Jeff Goldblum's champion, him becoming Professor Hulk, him going from Professor Hulk to whatever he is now).
I hate Mark Ruffalo as much as the next man (I think Ed Norton was a much better fit for Bruce Banner, plus his Hulk looked better) but Hulk needs his own property right now, and not guest features in everybody else's property.
