“Shark Warning” (*1/2 out of four) was yet another needless killer-shark movie about a man (Andrew J. Katers) who returns to his hometown 2 decades after a shark killed his brother; upon finding out that the same shark is still roving in the waters, he gathers up various friends and family (David Chokachi, Angela Cole, and others) to hunt it down and kill it once and for all. Film’s poster will likely remind you of “Jaws” and so will virtually everything else in the film, except that was done with supreme skill and tension and still holds up well nearly 50 years later. You likely won’t remember this one 50 hours from now.
