The Plot = A young boy witnesses his father shoot his mother and her lover and then himself, and is then sent to a mental hospital, but many years later he escapes along with his flute and goes on a killing spree. In the meantime a young girl Marion begins to have visions of him killing people through a rare blood transfusion between the two.
Okay Blood Song has some interesting ideas, but fails to execute them properly, for a start the whole concept of a girl having psychic visions of the killer could have been interesting but as the movie goes on it becomes it a bit dull, as there is absolutely no explanation given to why she has these visions, we know how through the blood transfusion.
I also liked the idea behind the heroine being physically flawed, which would seemingly make her a much easier target for the killer and possibly add to any sort of suspense later in the flick. Of course we don't get any of that. The film also throws in some long and drawn out drama scenes which takes away the tension out of this movie and plus while the murders and the final showdown are real highlights of this movie, it just takes too long and spaced too far apart, I mean at times I kinda forgot that I was even watching a slasher movie, it felt like a drama.
The positive aspects of this movie, is for one thing the climax watching the girl limp herself away from the killer and into some lumber yard. The change of setting proved interesting. And the performances were pretty good, Frankie Avalon was interesting as the serial killer even though he chewed the scenery practically all time but I found him fun and Donna Wilkes played the female lead pretty well, she hit the right notes at the right time.
All in all Blood Song is definitely an average 80's slasher with some pretty interesting ideas but are flawed to say at least I would only recommend this if you're a huge fan of 80's slashers.
