I have Taste the Blood of Dracula on my list of movies that could be remade far better than the original, because its plot was spot on, and somewhat universal.
Corrupt, perverted, decadent idle rich, who are so jaded to find new entertainments that one of them pays for a vial of Dracula’s blood. In trying to resurrect Dracula, though, they chicken out, so Dracula decides to punish them and their families.
There are several good variations on this theme, and it is easy to imagine corrupt, perverted and decadent rich people, you know, like George Soros, getting their comeuppance.
