The DC universe’s fishing expedition for a worthwhile film remains an ongoing upstream journey. James Wan’s foray into surf and turf sci-fi fantasy Aquaman (C+) has all the subtlety of a Super Bowl commercial, with either a tidal wave of action as bait or a dreamboat dilf as its siren call to adult moviegoers over the age of 13. Awash in largely inconsistent or indifferent special effects, the film is basically a palace intrigue barnburner between Jason Mamoa as the quip-happy mer-man hero versus Patrick Wilson as the bland opposing heir to the throne of Atlantis. It’s all underwritten, overlong and underwhelming but not without its occasional charms (although the flowing underwater hair effect is not one of them). Kudos to Nicole Kidman for classing up the joint. Otherwise it’s lots of inconsequential action, some akin to wrestling matches. If the film were a dish at a restaurant, it would ironically need more salt.
