Superman routinely and without care takes the mayhem towards the nearest structure (which is typically shown completely evacuated, unless the plot needs some drama), yet has to pause for effect before finally (and predictably) killing Zod with his bare hands.
That sort of reminds me of Christopher Nolan's first Batman movie, where it's a big deal that Batman lets Ra's al Ghu die -- ignoring the dozens of ninja assassins that died earlier in the movie when Batman blew up their headquarters.
As for "Man of Steel," as a lifelong DC superhero fanboy, it's hard for me to imagine a Superman movie that I'll be skipping. But this is the one. Maybe I'll rent the DVD ... one day. What the hell's the point of a joyless Superman?
