I'm not sure where, but somewhere along the way I got it into my head that this was an action-packed alien invasion extravaganza (kinda like CRITTERS or NIGHT OF THE CREEPS), but I was obviously incorrect cause this movie is boring as a bitch!
A tall alien (who gets maybe two minutes of screen time) is lurking around out in the woods hunting humans (much like PREDATOR did 7 years later with the same actor playing the alien!). His only weapon is a kind of parasite/frisby that he throws at people. It latches on and bites you to death or something. That sounds exciting, but it's not because the vast majority of the movie is people just wandering around in the woods or shitty looking buildings just talking and talking and talking.
The cast is impressive (Martin Landau, Neville Brand, Jack Palance, Ralph Meeker and David Caruso), but you've got to give them something to do. I'd be more interested in seeing what went on behind the scenes...I can just see Jack Palance snarling grizzledly while arm-wrestling Neville Brand as Landau laughed maniacally in the corner. It would have been awesome!!!
Zero nudity, almost zero action, really short shorts on David Caruso, lots of scenes shot in the dark, completely random PSYCHO reference. Skip it. The only reason to watch this movie is the scene where Jack Palance charges the alien while yelling "ALLLLLIIIIEEEEEEEEEEENNNNNNN!!!!".
