I just re-watched the original Superman move recently. It was, quite honestly, an incredibly well-made movie that took itself seriously enough that it wasn't scared to be genuine.

If it were made today, as soon as he put on the Superman suit something stupid and silly would happen to remind you that it's only a movie, Lex Luthor would be a damaged human being with daddy issues, and Lois Lane would have a skanky terminally-single friend who would tag along through the story so that she could voice the female audience members' lecherous thoughts.
