I want more outer space.
I want to see a great huge giant man from space. I want to see the Celestials. The one shot at doing the ultimate great huge giant man from space movie with Galactus was blown. I need consoling.
Similarly, I want to see Ego. He rules. The issue where Thor first visits his surface is one of my favorite things Marvel ever published.
Those are things that could work out perfectly in a Guardians of the Galaxy series.
I wish they could establish a world of street level characters similar to what Bendis did with Alias/Daredevil a while back. Too bad Daredevil's gone for good.
I generally want to see things get crazier in the next round. Thor was good but it wasn't really what I want from a Thor film; it was more like an origin story designed to take you to the point of doing a "real" Thor film. Hoping for space trolls with laser guns, more Warriors Three, etc. I want Flash Gordon with Kirby designs, basically. Third film goes out with Thor, Odin, & Loki vs Surtur at the gates of Asgard, like in Simonson's run.
I want the bigger, crazier Kirby ideas in a Cap movie. Robo-Zola and his weird mutants. Gigantic "sleeper" robots. HYDRA with more personality than the anonymous (and silent) stormtroopers from the first film.
I don't know if I want "crazier" from Iron Man. He's always been a fairly conceptually conservative character. If they can get around to him building a Hulkbuster and having a big dumb Hulk wrestling match in it, that's enough for me.
Use Ant-Man to get into the kind of super-science adventures you'd be having if the FF were around. Look at the recent comics: the Microverse and Pym Space and that sort of stuff.
More Clark Gregg. I don't care how, just do it.
