Despite intelligent commentary from comic-book figures such as Batman Beyond cocreator Paul Dini, Clerks film director Kevin Smith, and comics historian Trina Robbins, this hour about the history of the medium succumbs to the usual: campy narration (by TV Batman Adam West) and actors reading dialogue while we look at static comic-book panels. For every stab at much-needed analysis in Superheroes, there are minutes wasted on corny Zap! Pow! silliness. D+
