Compared to the book, yeah, it stinks...but that's really only because it got lost somewhere in translation from prose to screen.

Take it as it is, take it as a movie and its not half bad, the problem is that, once you leave the book behind what you have is an old fashioned B horror movie that is trying to sell itself in an era where B horror movies need the special effects of modern super hero movies and the basic plot of a Dick and Jane novel.

And then, in many ways, it's just too expensive. It feels like a classic Drive-In horror flick, but it looks like a block buster. Tone down the budget by a few million and make it a direct to video movie and it would have cult classic status already...despite the people that actually read the source material.

The acting is good, the special effects are too good, the setting is cool, but the plot hurts a bit and the fact that Duddits is Intellectually Disabled is inevitably going to put off more that a few viewers.

Really though, what you have is a great B Movie Drive-In fair that somehow got an actual budget wot work with. And you could do a lot worse in this Post New Hollywood day and age.
