I don't "hate" SR, I just think it was misguided and disappointing. I didn't want to see a zillion-dollar fanfic about the Donner Superman, I wanted to see Bryan Singer's original reinvention of Superman. What made the X-Men films work so well is that they weren't a slavish recreation of something from the past, but a radically fresh and different take on the X-Men that still managed to capture their essence. That's what I wanted Singer to do for Superman, but he didn't even try, because he was too busy being a fanboy, and trying to recapture the flavor of a movie that was a relic of an earlier time and didn't age well enough to be worth resurrecting today.
I also didn't think much of the casting or the directing. Routh never worked as Superman for me. Kate Bosworth was breathtakingly gorgeous but breathtakingly wrong for Lois. And Singer seemed to be coaching the entire cast to dial their performances down to the most subdued level possible, so the whole thing lacked energy and intensity.
By contrast, I do
hate a lot about Man of Steel
. It has some great ideas here and there, the second act works pretty darn well, and unlike SR it has a great cast (except for Kevin Costner, whom I've never liked, and Amy Adams, who was merely okay as Lois, though better than Bosworth). But the third act is a hollow, soulless exercise in excess, and the story doesn't let Superman be Superman, reducing him to a passive and ineffectual lackey in a story about the heroism of Jor-El, Last Father of Krypton.
