In a straight-jacket, hood, chains and brandishing an axe, Moonstalker's crazed killer Bernie makes for a memorably imposing maniac, which is why it's a shame when he swaps this distinctive garb for a cowboy hat, dark glasses and and a plaid shirt. But even though he loses a lot of his mystique with this change of outfit, the drooling psycho remains as mean as ever, killing off most of the film's cast before the closing credits. Along the way there's quite a bit of hokey gore (rubbery body parts and splashes of blood), just a little female nudity (one of the girls strips off to take a shower with a young man), and, with the film taking place at a wilderness counselor's camp on a snowy mountain, lots of sitting around camp fires (in the film's most macabre moment, even the dead enjoy a sing-song around a roaring fire).
It's certainly no classic, but as low-budget late '80s slashers go, you could definitely do a lot worse than Moonstalker: the film is never boring, the sub-zero setting is a nice change from the traditional summer camp, the characters are likeable (the girls are all very pretty, which helps), and no-one is safe, which makes it one of the less predictable examples of the genre. Only the score really disappoints: it's a third-rate rip-off of John Carpenter's iconic music for Halloween.
