There were so many team changes over the years with the Avengers that you could put together a team of just about any character in the Marvel universe that you wanted. There was never a constant team that existed for more than a few dozen issues. Change was the name of the game. Animation, as in Spider Man & Transformers, probably works as well, if not better, than live action. I don't visualize a problem with authenticity or quality if Universal decides to go this route.
