“Shark Bait” (** out of four) was a not-bad horror suspense thriller about a group of friends (Holly Earl, Jack Trueman, Catherine Hannay, and others) out jet-skiing at sea who become involved in a collision and are (what else?) preyed upon by deadly sharks who sense blood in the waters. Umpteenth killer-shark movie is better than most with crisp cinematography from Ben Moulden and good production values but others may find it too derivative of the first two “Jaws” movies. By now, there have been so many shark attack movies that they’ve just about lost their teeth.
