I just saw this TV-made movie on 35 mm print last Monday. It's supposed to be a horror movie, but it's almost a kiddie picture. The film's not very good, to put it mildly (though it was directed by veteran Gordon Hessler), but its cheerful jerkiness is entertaining throughout. Wouldn't you laugh at Gene Simmons acting badly and throwing flames out of his mouth to the sound of a lion roaring? The Kiss guys have also raybeams coming out of their eyes! And they can fly!
As for the music, I don't really care for Kiss, but some of the song are actually pretty good power-pop items.
Here's a sample from the film with "Hotter than Hell" to other lyrics.
