The Waystop is impressively written, and stands out as an adventure that pushes the boundaries of quality storytelling in AL.
The B-grade horror opening notwithstanding, the adventure has a layered story that features a fantastic cast of NPCs, an incredibly atmospheric set, and some very creative uses for a monster from Mordenkainen's that is seldom seen. Every clue in the adventure is deliberate, and every scene with an NPC is an opportunity to peel back their masks or to uncover more of the plot. Having multiple twists and endings (some mutually exclusive) adds to the replay value.
Players who are more passive, or who are more used to the typical hack'n'slash adventure may require some handholding. While preparing the adventure, I also found it helpful to read the Dramatis Personae after the Background, as a good grasp of the NPCs and their motivations can help put the rest of the story into context.
