Jason Mamoa reprises his role as the aquatic avenger from Justice League in this shallow but energetic sci-fi fantasy. Director James Wan (Saw, Insidious, The Conjuring) goes big-time, big-budget with this CGI-saturated underwater epic. It's 50 percent Indiana Jones, 50 percent Star Wars and 50 percent Thor—and at two hours and 23 minutes long, it's about 50 percent too much film. But it's a good indication that Warner Bros./DC has finally crawled out from under all that "grimdark" baggage and is ready to have some fun.FULL REVIEW:Bright direction and epic action keeps watery superhero afloat by Devin D.
