Blood Song is the story of slightly unattractive, handicapped lead Donna Wilkes (who would later look hot as shit in the 80's movie Angel) whose leg accident resulted in a blood transfusion with a mental patient who witnessed his family kill his cheating wife, the home wrecker, and then himself when he was a child (the child's reaction to this in the film is SERIOUSLY one of the unintentionally funniest scenes ever. I spit my drink out everywhere and just about lost my shit). It is then that Wilkes begins seeing everything the now grown up, killer mental patient (Frankie Avalon in an against-type role) through visions, which involve him escaping the looney bin and hacking his way to her home town, where he starts chasing her around with psychotic glee. Blood Song builds itself upon hilariously bad acting and plot holes. The death and gore are fine and Avalon is fun to watch play a demented villain. Also, the ending is fantastically over-the-top in its grimness. Overall, a somewhat amusing 80's slasher film.
