One wonders why the OP imagines anyone would give a rat's backside about their opinions on Ravenloft.
The non-human vampires of Ravenloft are so good, I made them core for my non-RL games.
I know Ravenloft was originally a "demi-plane," of some variety, but I'm wondering--is the Ravenloft featured in Curse of Strahd supposed to be within the world of Forgotten Realms? They've been pretty gung-ho about having FR front and center as the setting so far.
