It seemed to me that many people cited the simplicity of the Superman character (as just Superman not Clark Kent-as Superman)as the main factor in their not liking Superman. I personally have no problem liking both, I don't necessary feel that I have to subscribe to the prevalent view of Superman in the movies. In fact, I think they're more ambiguous than people give them credit for. In Superman II one of the more heartwarming scenes for me is when Superman takes Lois to the Fortress of Solitude and she says "Wow so this is where you live" and he replied, "No, actually I live three blocks from you."
