I was left a little cold by the second Superman trailer--why is it that when Supes is flying at 400 mph, his hair moves as if there's only a light breeze? And why is Kevin Spacey doing Lex Luthor as if he was K-Pax's evil brother? Shouldn't there be a no-camp mandate? And that scene with Lois, Perry, and Jimmy doing the "It's a bird" routine feels like a stilted rip-off of the wonderful J. Jonah Jameson office scenes from Spiderman 2.
All of that said, AICN has the first early review of Superman Returns, and it's quite positive, although for reasons I don't find particularly convincing. Still, we DC partisans must hope for the best.
If only Wolfgang Petersen had been allowed to make Superman vs. Batman. Well, a boy can dream.
Update: In the comments is a link to this extemely sophisticated fan-film trailer for Superman vs. Batman. In all honesty, I'm not so sure that the Singer-helmed Superman Returns trailer is more enticing.
