Good enough for me. I should really rewatch that flick. Katherine Ross never gets enough props and Paula Prentiss is fantastic as her smarmy friend.
As for the other 20 obscure 80s movies, since DG asked so nicely...
Dawn of the Mummy
The Church
Q: The Winged Serpent
Alligator
The Stepfather
I, Madman
Phantom of the Opera '89
The Dorm that Dripped Blood (aka Pranks)
Dead Ringers
Macabre
Lair of the White Worm
Vamp
Basket Case
Frightmare
Effects
Hell Comes to Frogtown
The Carrier
Bad Dreams
Death Warmed Up
Body Count
Actually, I could probably do another twenty on top of those.
