I actually have a fondness for Christopher Lee, but this just wasn't up to his other performances... and he was one of the better actors.
The film does not live up to its premise. It's not that scary, it's overly melodramatic, and it draaaaaags. Every time I thought, "Oh, HERE comes the good part" the good part never quite arrived.
The Evil Ones aren't at all convincing. Most of the other characters were also lacking in depth.
Perhaps if I'd been in the proper frame of mind, I might have enjoyed some MSTie-fication at this film's expense, but.... Naaahhh... Didn't really seem to be worth the effort. It wasn't really very good, it wasn't really very bad, it was just mediocre.
