In spite of the early "girl gets her face ripped off" scene, Book Of Blood takes a while to get going. For a while there I was wishing it would hurry up and end.
Eventually that feeling passed and I found myself completely drawn in to a pretty damn interesting ghost story.
An author who writes and teaches a class about paranormal activity holes up in a supposedly haunted house with her friend-with-a-lot-of-high-tech-equipment and one of her students, who has psychic visions. Crazy shit starts happening.
I've discovered the hardest thing in the world for me to do is review things that I enjoyed. I can never think of anything to say about them.
I liked Book Of Blood. I really did. That's all I've got.
That and an effective ending was marred by a framing device. Most of the movie is a story that the main character is telling. So after a very effective ending, a second and kind of pointless ending is tacked on for bad measure.
It doesn't ruin the movie, though.
End of line.
