I post in the voice of Christopher Walken
Like you, I don't find all the tropes of gothic horror innately wrong, but the presentation of them could use some freshening up. And a few new ideas like zombie apocalypse or illusion masquerade will freshen up the dustier or repetitive areas.
I have no issue with freshening up. I do think I would disagree with a lot of posters about how best to go about freshening them up though. And zombie is something Ravenloft already incorporated (Night of the Walking Dead for example). I think you can blend other genres in. The issue is the core of it needs to be gothic or its all just superficial blending. The blending should compliment the core concept, not fight with it or distract from it (or blur the setting).
