Bob Clark (PORKY'S, A CHRISTMAS STORY) and screenwriter Alan Ormsby (MY BODYGUARD, CAT PEOPLE) get extra points for an early and knowing response to the reintegration process of U.S. soldiers returning from Vietnam. At this late date the film has no value as a horror flick, its scares predictable and without any sense of genuine menace, but as an allegory of the physical and psychological distance Vietnam vets often faced it's quite affecting. I don't know how common was the knowledge that many vets had problems with heroin, but Clark/Ormsby knew. Anti-hero Andy Brooks, who in a Monkey's Paw-like resurrection, returns home an affectless zombie-vampire monster, shoots up his victims' blood like an addict getting a fix. I say "anti-hero" because for all his bloodletting Andy is a victim of multiple curses: a domineering father who drove him into the military, a war that kills him, and a mother's selfish love that brings him back. The ending is really quite sad, but I won't give it away.
