Comic accuracy can have nothing to do with whether or not a movie succeeds creatively or critically. But comic movies are supposed to appeal to comic fans. If not, then why wouldn't the studios just create brand new superhero teams where they wouldn't have to share profits with Marvel? At that point, comic fans want this or that in comic movies, of course, and characters maintaining similar looks and backstories matters from that point of view. I personally understand that film and comics are fundamentally different media, and require different approaches. But I think some of what has become conventional wisdom, particularly with this franchise, is flawed logic. So, for example, the costumes they're wearing here just look like garbage for the most part. Most here seem to agree. So. . .why not try something else? After the success of Avengers I figure they would be open to that, but I guess not.
If it's not "stealth Motocross" then it's not believable!
