Did you ever end up watching Bloodlust (1992)?
I've seen a couple of Rollin's vampire movies, and like Lemora: A Child's Tale of the Supernatural and Grave of the Vampire (1972), though not for the same reason, they feel like maybe something I shouldn't be watching.Not yet, I'll probably get to it eventually.
Requiem pour un vampire (1971)
My 200th vampire movie! This one by Jean Rollin, a French cult director that from the 60s till the early 2000s directed nearly a dozen vampire movies. His work tends to walk the line between art films and sexploitation. Even more so with Requiem for a Vampire. It's so surreal, much of the movie doesn't have any dialogue and it's unclear if scenes are intentionally or unintentionally funny. There was also more eroticism than I've seen in his other work.
In part this film was fun(ny) with cool imagery. But it dragged in places too, feeling much longer than it actually was.
