I haven't read the book, so this is just about the movie.
I found it to be a wonderful example of So Bad Its Good
. Hayden Christianson's "acting" is hilarious, and gets better if you pretend that every time he opens his mouth he's Anakin from Attack of the Clones
saying "I murdered them like animals, the women and the children." (Your Mileage May Vary
, of course.) The plot is nonsensical, the main character is a total jerk, and the villains are fairly unmotivated. All in all, a good movie to see with a bunch of friend in a setting where you can deride it to your heart's content.
