This is tongue-in-cheek horror with some decent comically sinister characters. Four young people descend on a lakeside community for a romp and a bit of fishing. One of them is there to test the water for contamination. There is some creeping menace about the lake as people are going missing. My favorite character is a one-eyed gas station man called Willy. He reminds me of the type of character John Carradine used to play. Willy drawls out lines like "Them fish are getting stranger and stranger" as reports of ferocious pike attacks have been reported. I think this movie just about gets away with it as family entertainment. Parents might like to note that the profanities are of scatological-type only. There is some sexual innuendo and brief sounds of sexual activity and brief nudity which is not full on.
