Iron Man is an appealing superhero movie. It's also clunky. It's welded together out of disparate pieces that clank and ping. Though at times it's leaden, Iron Man also has enough moments of pizazz to intermittently soar.
Not only is it a good comic book movie (smart and stupid, stirring and silly, intimate and spectacular), it's winning enough to engage even those who've never cared much for comic books or the movies they spawn. Like me.
