“Deep Blue Sea 3” (** out of four) was a shallow horror thriller about a marine biologist (Tania Raymonde) and her crew of scientists who are doing research on a remote island when her ex-boyfriend (Nathaniel Buzolic) and his rogue team show up attempting to capture three sharks on the loose who turn out to be bloodthirsty and savage and before anyone can say “Jaws” they all find there is blood in the waters. Third in an unexceptional series that began all the way back in 1999 isn’t bad and has a few minor scares and shark attack sequences but not enough to make it stand out from the rest of the pack and it’s pretty forgettable. By this point, there have been far too many killer-shark movies and they no longer have the same teeth they once did.
