“Deep Blue Sea 2” (*1/2 out of four) was a fairly awful sequel to the original which came out nearly 20 years ago about a group of scientists (Danielle Savre, Rob Mayes, and others) who are led by an unscrupulous billionaire (Michael Beach) to his private resort where he is doing experiments on bull sharks but they soon realize they’re all on the menu. More-or-less a remake, rather than a sequel, to a movie that was pretty weak to begin with but at least the original had some thrills and unintentional laughs. Thomas Callaway’s striking cinematography provides only highlights but otherwise this is a real bore.
