I really wish the MCU would start including more from 2008's The Incredible Hulk. It is canon to the franchise but other than having the Hulk in the Avenger's, they haven't done much else with it. I would like to see Agent's of Shield tackle some of that. For example they could get William Hurt to come on the show as General Ross. Or maybe they can finally show us what happened to Samuel Sterns and perhaps show him become The Leader. Liv Tyler as Betty Ross would also be a nice character to see return at some point, and I wonder if the Government still has The Abomination secured.
Hell, I think they should just make The Incredible Hulk 2 staring Mark Ruffalo. They can make a good one and maybe we can see Red Hulk?
