Watched Re-animator myself for the first time, also after going on an HPL kick (haven't read that short story itself, though). Enjoyed it a lot - it's the kind of horror flick that knows it's a bit ridiculous and has fun with that, without throwing in the towel for outright goofiness. Some pretty unnerving stuff in there, brrrr dead people. Jeffrey Combs is fucking hilarious, so many inappropriate one-liners.

Also Barbara Crampton is hawt!
Also watched From Beyond right afterward, also HPL-based and with the same director plus Combs and Crampton. Again, good stuff - definitely worth a look if you end up liking Re-animator, burgerking.
The Fly (1986) is brilliant, rancor. A body-horror milestone from Cronenberg with great lead performances from Jeff Goldblum and Geena Davis. The only thing that's dated about the film is her poofy hairdo, the practical effects surrounding Goldlbum's disintegration are still horrifying and the human aspect is timeless. Hellraiser likewise is one hell of an s&m-themed horror show. Scanners is nowhere near as strong as those two, the body of it doesn't live up to the iconic opening scene or the gruesome climax. Michael Ironside rescues it mostly, Revok is a great antagonist. The lead actor is either literally brain-damaged, masterfully portraying brain damage, or just a
really shitty actor.
