What is your favorite iteration of the Ravenloft Campaign Setting?

So, with the new announcement, what has, so far been your favorite gothic version of D&D? I’m also including MtG’s Innistrahd here, and the Victorian-set Masque of the Red Death. I’m unsure if there was an actual Ravenloft product for 4E, but I do remember mentions of a “domain of dread” and possible ties to Ravenloft with the Raven Queen (and Shadowbane family).

Speak up, and tells us what you liked most about the various versions, and what you think they could have done better!
