I post in the voice of Christopher Walken
Mind you, I don't claim to be well versed in Ravenloft lore, so I'm coming at this from an outside perspective during the present time. You were introduced to it differently, and are certainly more passionate about the setting, at least for the Black Box, which I presume is the first setting product for Ravenloft, outside of the one off adventures like I6. Which is great, but nostalgia can sometimes blind us to shortcomings in things we remember fondly. I'm certainly not immune to doing that for the things I like in D&D. Ultimately, I guess what I'm rambling on about is that when Ravenloft is updated to 5e, it probably should change to some degree with the times as well. If it can't do that without remaining staunchly Ravenloft, well, the Black Box is still there for those who enjoy it.
Personally I don't think WOTC is capable of producing content as good as the black boxed set. At least for me, I've never really liked WOTC adventure or setting content. But that is separate from issues of nostalgia and problematic content. What I am trying to do is simply cast more light on the original entries because I feel people are simplifying in their characterization of it, and I also feel the critical lens being applied is too sweeping and will potentially throws the baby out with the bath water. Am I blinded by nostalgia? In this case I don't think I am. I can criticize the things I loved growing up when they turn out bad. There are tons of books I read and loved that when I go back to them, they make me cringe because the quality really isn't there. But the black box is something that I call a masterpiece because I am always surprised by how good it is on review. It has a clear vision and philosophy about horror, which it expresses in an engaging and evocative way. I think anyone who grew up on a diet of classic horror can appreciate the tone it achieved, and I think it just works wonderfully (at least for me) at the table. This was also a book that showed me D&D can be so much more than Forgotten Realms and Greyhawk. The two settings that impressed me most in that time were Ravenloft and Dark Sun, because they were startlingly refreshing. And Ravenloft breathed. You could feel the effect that black box had on a lot of the subsequent novels and supplements. All you need to make a successful Ravenloft Campaign are the black box, an adventure like Feast of Goblyns, and a handful of Van Richten Books. I had the entire line. But IMO the magic occurred in that span of material.
