This sequel to "Watchers" is just a reworking of the original. Or, more accurately, it uses Dean Koontz's original story as the basis for yet another "Predator" knock-off. Pretty lame, with some terribly unconvincing effects (check out that severed head), but an amazingly well-trained dog yet again saves the day (i.e., at least makes the movie bearable). (*1/2)
