Mad Doctor of Blood Island

I recall seeing this film at a drive-in many years ago. While I admit to a tendency of enjoying bad movies, this one had some allure because of its exploitive bent. Yes, the script is bad, the acting is also stinky, and there is some screwball operating the camera who keeps playing with the zoom lens, but the movie attempted to expand the boundaries of shock value in its day. An island monster is running around making hamburger of his victims. A not-too-savvy young American with a Ricky-Nelson haircut is on the case. Care to guess what happens next? When I saw it as a teenager it had an impact, but it probably rates as a grade D horror flick. A product of the Philippines, I believe. Am I recommending it? Only for fans of the genre.
