it's obviously not supposed to be "great" movie, but for the hilarious horror/comedy it is, one would take this as it is. a breath of fresh air for the over bloated 70s/80s horror movie market. it doesn't make a lot of sense, but it shouldn't have to. viewing this ridiculous movie for what it is, it is a beautiful depiction of a shitty movie made enjoyable through writing and acting. oliver reed does a magnificent job playing both lead roles, even while switching between the two. looking for a well written movie with unexpected plot twists, it is obviously not going to rate very well. it was 1980, why would you make a super deep movie with every opportunity for criticism? while writing this i would obviously assume it's not to be under the scrutiny of every movie buff this side of the Mississippi. take it for what it is, a ridiculous horror movie with a brand new twist on the old, often retold, story of the doctor that creates more than what he meant to create. great for what it is, and hardly a moment wasted. 8 thumbs up.
