Who knew ex-teen heart throb Frankie Avalon could play such a creepy, and yet, hilarious killer? Blood Song (also known as Demon Slayer) starts off with a father coming home early to discover his wife in bed with another man. This results in the husband gunning down the wife, her lover, and then himself. All the while, the son witnesses the heinous act and naturally begins to play the flute. Well, wouldn't you!? Thus, we have the setup to Blood Song, a cheesy 80's slasher that I somehow missed growing up.

Sent to a mental institution, the flute playing boy-turned flute playing Frankie Avalon, escapes from the institution (naturally) to a destination unknown to him. Accompanied by his trusty flute (which he makes sure to play constantly), he kills anyone who doesn't like his "music". Meanwhile, we're introduced to our heroine "Marion" -- a high school girl, whom has a crippled leg after a car accident years prior. Forced to wear a leg brace (until she replaces it with a cane later on), the girl begins seeing visions of a flute-playing man killing people on more than one occasion. Who could this mysterious man be and why is she linked to him? Hmmm..

Blood Song offers some interesting ideas, but fails to execute them properly -- For example, I like the whole concept of the girl somehow being psychically linked to the murderer and forced to witness his crimes, but when it was time for the girl to start seeing Frankie's latest victim we have to first sit through gratuitous close-up shots of her eye, before transitioning into some kind of horrible pixilated colorization. Once was definitely enough, but this happens more than a few times in the movie.

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, but one could hope. The film also throws in some unnecessary melodramatic scenes that just seemed entirely out of place and drawn out. Like one scene, where after fighting with her dad, the girl goes to a pier to cry and sulk around for a few minutes, dampening the already mediocre-paced flick. Later on we're also given a boring 4-minute walking montage of the girl going to the beach. Was watching her do all that damn walking really necessary?

We're given a half-assed explanation as to why the two are linked and later shown a more than coincidental reason for them to finally cross paths, but you can't expect much from the script considering the decade it birthed from. The kills were fairly minimal and we really don't see any gore, but there are a couple somewhat decent bloody scenes (axe to the face), but that's not saying much. The movie's climax isn't entirely a waste, watching the girl limp herself away from the killer and into some lumber yard. The change of setting proved interesting at least, but of course it was ruined by a couple unintentionally funny sequences (fork lift).

Blood Song is an average 80's slasher, with Frankie surprisingly playing the creepy killer role pretty well and I liked some of the ideas we're given, even though they were poorly executed. However, with its many flaws, I wouldn't recommend giving this a look unless you're a huge 80's slasher fan.
