I happen to love H.P. Lovecraft's works (I've read everything) and I doubt anything will ever match the brilliance of his stories, but I thought
Dagon, The Resurrected, Re-Animator were very enjoyable fims...
I however was completely bummed by the silent-film adaption of
Call of Cthulhu. It was boring and ugly...
I'm sure there's more Lovecractian films floating around... I'll dig up some more titles.
Here's a good link:
