I grade on an odd curve, it's probably more a straight-B movie but that felt too low. Yeah it is almost a BB feel. I really liked it, more on reflection, and I'll see it again on release but its not quite the Superman movie I would have liked. Still, better than SR more action and look than the Donner film(s) but still lacking "something." I'll stick around for the rest of today to answer any questions/concerns. (Spoiler Coded, of course.)
As someome who loved Batman Begins I really have no worries that I will love this movie.
