This whole generation of Marvel animations, which began with the groundbreaking X-Men series, is of an extraordinarily high quality. Their visual style is influenced by the best of the comics' artists, the protagonists are properly fleshed out, and--proving that cartoons don't have to be dumb--the plots and story arcs often have the kind of sophistication you'd expect from the best kind of adventure novel. This example is typically faultless in execution and, unlike most Saturday-morning fodder, bears repeated viewing. --Roger Thomas
