Thinner.
I'd give it a 1 out of 5. The premise was good, and the script was okay, but the acting was terrible. I think the only actor who came off well was the one who played the Gangster, Richie.
I am a big fan of the book, but once again, it's an example of what NOT to do with a Stephen King adaptation. It had no heart, no soul, and actually was so mean spirited that the characters were two dimensional, just out to hurt one another.
