One of his worst,I found was SUMMER OF FEAR,a rather bollocks TV movie.
Deadly friend,whilst no classic was rather fun.
Deadly Blessing was not bad.
Scream as we all know,brought the slasher boom back.
Shocker was IMHO too much of a Freddy Krueger imitation.....
The People Under The Stairs was nuts!
The Serpent and The Rainbow was another I could never really get into....
