There needs to be more people talking about this movie. It's a movie that borders between good-bad and just bad.
The virtual reality scenes, while kind of cutting-edge at the time but not really, are just laughably bad by today's standards.
And I felt that Jeff Fahey gave an awesome performance. He was a very convincing mentally disabled man turned genius omnipotent maniac.
I also agree that the controversy around using a Stephen King novel and his namesake for marketing, and then totally mutilating the story sans one scene, makes this movie even more interesting.
