as long as its fun, and entertaining, and doesn't take itself too seriously. No killing important characters left and right and no long boring monologues about love or duty or whatever .

I don't see why it won't retain the same quality as the first one... With the origin story out of the way, I expect Iron Man to interact with the Marvel U.

I could see it working really well with War Machine and Black Widow sub-plots running with Iron Man's interaction with Fury/Government and Whiplash
