D&D 5e - Curse of Strahd

Curse of Strahd (CoS) is one of the more well-regarded and fully-covered adventures in 5e D&D, so I’m not going to belabor an explanation of the premise. In brief, you get pulled into the demi-plane of Barovia, run by the mad demigod – and vampire – Strahd von Zarovich.The entire campaign is interacting with the denizens of this macabre land with the goal of killing Strahd and escaping the cursed land. It’s gothic horror, so the tone is more dour than the standard D&D fare.I want to focus on some of the things Strahd does really, really well, and a couple that it fails on, in order to frame its popularity in 5e.
