As someone who has mostly played D&D 5E in recent years, this adventure is a wonderful introduction to a new system. There are odd elements in some maps, to be sure --- I was particularly struck by the kitchen and pantry that were not connected --- but I really enjoy the way that classic dungeon crawl elements are loaded down with opportunities to approach play in different ways. In comparison with D&D adventures, this book felt almost overloaded with small story moments.
In play, the adventure feels diverse and fun, with different kinds of activities and adversaries. For a low-level adventure, I can't ask for much more.
Edit to add: the now-repeated complaints in negative reviews about "SJW" content make no sense without specifics. This book doesn't engage in real-world politics, from any perspective.
