Aquaman is very goofy, and if it was an hour shorter, it would totally be worth your time. As the affably bro-y fishman, Jason Momoa punches CGI monsters and supervillains who wear stupid costumes; he also, in the film’s best moments, flips back his dripping hair and, angling his shirtless torso for maximum gleam, all but winks at the camera as an electric guitar wails. Eagerly and clumsily, Aquaman dispels the joyless grimdark that’s infested other movies based on DC Comics, and director James Wan delivers some genuinely great stuff—a horror-tinged encounter with dagger-toothed wretches from the deep, a psychedelic submarine chase through a fluorescent Atlantis. But he’s hampered by too much plot, dreary politicking that aims for Game of Thrones but lands at Phantom Menace, and a plasticky sheen that cheapens everything from the bad guys’ Power Ranger suits to the digitally de-aged faces of Temuera Morrison, Willem Dafoe, and Nicole Kidman. Aquaman’s super fun when it embraces its silliness—there’s an octopus who plays the drums! there’s an army of cranky crab-men!—but by the end, it just feels bloated and squishy. by Erik Henriksen
