And of course, you absolutely cannot beat the original I6: Ravenloft.
I personally find that module terrible. It's essentially everything later products warn against... a large collection of rooms featuring "scary" monsters and random encounters with d4+1 wolfwere golem liches.
Many of the published adventures were awful, and encouraged the "Sliders" feel of the way many bad Ravenloft games were run, where you ported into a domain, beat the big boss, and moved on to the next in a constant search for your golden ticket back home.
As a whole, the 2nd edition Ravenloft modules suffered from the style of adventure writing at the time. Choo-choo! They're usable, but they take some elbow grease. There were some decent ones. Children of the Night: Created, Bleak House, Carnivale, Night of the Walking Dead and the Evil Eye were some of the better written ones. Circle of Darkness was also pretty good, as it offered a darklord a chance at redemption. I was a player in Servants of Darkness/The Shadow Rift, and Neither Man nor Beast, and enjoyed those, but dont know how much was changed from the source material. If you can dig up the old dungeon adventure, The Last Dance, I enjoyed it as well.
I prefer a more subtle version of the setting than many of the written modules implied, where it could be mistaken for our world, and where the supernatural wasnt glaringly obvious to everyone, with skeletons walking the streets during broad daylight and giant walls of gibbering skulls appearing constantly.
The worst of the offenders was the god awful Death Ascendent trilogy. While the modules would frequently ignore the setting advice on the difference between gore and horror, these three were among the worst. Slapping blood fountains and giant skulls on everything doesnt make it scary. Not to mention it nuked one of the better domain lords and left the world with Halloween town out of the Nightmare before Christmas.
