Now here's a movie!
A woman is raped by some big-ass fugly bug monster and she gives birth to a kid who inheriets some of his Daddy's nasty habits. Like drinking blood,cannibalism,and ripping peoples heads of. And wotta cast! Luke Askew,RG Armstrong,LQ Jones, Ronny Cox!
The transformation scene is really wild. I seen this in the theater back in '82 at the age of 20...kids were screaming their heads off. Good times. :)
