“Sex Guaranteed” (*1/2 out of four) was a terrible movie, guaranteed, about a loser named Kevin (Grey Damon) who swears off sex to win back his fiancee but happens to meet a beautiful escort (Bella Dayne) at the party of an eccentric millionaire (Stephen Dorff) and realizes she may have the spark he needs to turn his life around. Dorff’s amusing performance is the only salvation for this moronic and contrived story. Won’t someone please rescue him from this direct-to-DVD junk?
