Xmen costumes: they dont have to be exactly like the comics like what fanboys say, the ultimate suits were alright. I think they could definately have better suits than what they settled on for the xmen movies. black biker suits...meh.
Superman suit: fanboys complain that the blue is too rich, the red is too burgandy, and the yellow in the S is too mustard-y. The S is also too small, the cape should be more of a fabric, than hard leather. the S on the belt is useless and unecessary, and Brandon Routh looks like a fresh face youngster. - thats what ive heard from the Superman Forum.
