The kids-in-the-woods genre isn't a hard one to rise to the top in, yet this film succeeds on its own. A genuinely well-made horror movie with several truly original, creepy images (the man coming out the waterfall!) and an excellent hand-to-hand combat finale. Shot on a genuine shoestring, this film betters by miles any of the studio-financed atrocities that came in the wake of the first Friday. I found the acting and dialogue convincing, at least for horror movie standards. And the photography is grainy and low-fi in an ominous way, without looking unprofessional. This is one of the best horror films of the 1980's, seriously underrated.
