If Marvel catered to people like you their shyt would flop.
Again, and hopefully for the last time:
Nobody gives a fukk about a random suit of armor flying around on screen. Go read the reviews. Everyone praises RDJ for all 3 movies, to the point of saying it's impossible to imagine anyone else playing the role. If what you're saying is true Marvel wouldn't be spending weeks negotiating with RDJ, they would've kicked him to the curb like Terrence Howard and Edward Norton.
And Iron Man is not a major character. Cut the bullshyt out. Wolverine, Batman, Spiderman, Superman, those are major characters. Iron Man and The Avengers in general have always been b-list.
