I read the book this was based on a few years ago. I couldn't give a bollock's-arse what the consensus is on Dean Koontz' work, I've really enjoyed the books of his I've read. Odd Thomas and Intensity (which inspired the ace French horror film Switchblade Romance) were particular highlights.
The film's a pretty faithful adaptation of the book, so if you've read that and enjoyed it, you'll probably like this. I did. So there.
