I haven't read Dean Koontz's novel, but most of this movie's faults can be traced back to predictable and simplistic script, which bears a strong resemblance to "The Eyes Of Laura Mars". Otherwise, this is an entertaining horror thriller, with trippy "tunnel vision" (literally) sequences, flashes of dark humor and the usual good performance by Jeff Goldblum. The "good vs. evil" climax does come off a bit cheesy, but that doesn't happen because the effects are not good; it happens because of the way in which they are employed. (**1/2)
