Not to mention there are so many more original concepts that could be turned into movies, I see no future for Ravenloft on the Silver ScreenThe reincarnated love isn't actually part of Dracula's story but Francis Ford Coppola inserted it into his Dracula movie so, yeah, it'd look like a swipe from that, rather than potentially being the other way around.
But yeah, given how much of Ravenloft is wrapped up in book and movie Dracula tone, other than him having a problem with a lich rival, it'd take some serious work for it to look novel to a new audience.
