Well, a Black Panther movie without Storm would be lame as hell. The two of them running around being awesome would be a great film.
It'd be like Beyonce' and Jay-Z's On the Run tour.
In any case, Iron Man 3 made me want to kill myself. I'm not sure how much more of Tony Stark I can take. His... smart-mouthed-billionaire-genius-with a heart-of-gold cliche' has gotten stale pretty fast.
