i dunno.the outfits made sense to me cause leather gives you a lil bit of protectioni think,least what i heard, i dont wear leather so i wouldnt know either way. and the first x-movie the outfits were basically the same probaly because they didnt have much of a budget and in the next two movies they were changed a bit, at least wolverine's was,his is the only one i can rele remember being different. it was designed a bit wolverineish,like with the adding of either yellow or some type of color like yellow and i just looked at some of the other costumes like storms n it had white/silver colored parts. as for singer having superman's costume being the same design as the comics, i dunno. i dont have an argument for that cause i dont know how to describe it rele. all i can say is that sometimes ya just gotta change some things because some things cant translate to film very well. Oh and i just thought of a argument for why singer had the costume be the same design from the comic, although its not a argument im making to defend singer, cause i havent even seen superman returns n prob wont cause the whole idea of making a movie that isnt rele a sequel or a remake, but some kind of alternate sequel? or whatever it was, kind of turns me off. anyway my argument would be that well since the movie isnt a remake but a sequel of some kind to the christopher reeves superman flicks are that well for him to change the costume wouldnt be consistent with the movies that came before it. so that right there is the only reason i can come up for it from a logical point of view i guess, but whatever.
