“The Meg” (*1/2 out of four) was an utterly generic and dull shark-thriller that could have easily been titled “Deep Blue Sea 3” or “Sharknado Returns” about a daredevil rescue diver (Jason Statham) who has to rescue several (Bingbing Li, Rainn Wilson, Cliff Curtis, and others) in a sunken submarine but they all soon realize they are under siege and endangered by a 70-foot shark! Toothless movie offers no scares and no thrills and winds up a real time-waster on both sides of the camera. Even Statham’s effortless charisma can’t keep this from being dead in the water.
