“The Lone Paddler” (** out of four) was an obvious horror melodrama about a group of friends (Vasilios Fillippakis, Emilie Moffat, Andrew Martin, and others) who embark on a camping trip but soon find they have been targeted by a sadistic lunatic (Scott Graham) intent on tearing them all apart, physically and psychologically. Good production values fail to bring fresh paint to a well-worn canvas and tired story. Film is crisply shot by Brian Berneker and decently acted but is only for those who’ve never seen “The Texas Chainsaw Massacre” or “Deliverance” (or any of its imitations). Not to be confused with “The Lone Ranger.”
