The second feature of John McNaughton (Henry: Portrait of a Serial Killer)for my money, more interesting and enjoyable (if also somewhat more scattershot in its focus) than the firstis an SF horror comedy about an exiled extraterrestrial killer in a makeshift human body who needs to borrow the heads of others to survive. Happily, this permits most of the members of the cast to play the alien at one point or another; more generally, it serves to illustrate a highly jaundiced view of urban lifewith the implication that even the nihilistic extraterrestrial is preferable in some ways to many of the self-absorbed creeps who cross his path. McNaughton keeps things moving with humor, gore, and intelligence. With Rae Dawn Chong and Tom Towles (1989). (JR)
