I think this is the best module of about 25 I've read so far. Many are great but most of them have some big flaw, usually in a layout that makes them hard to digest (and hard to DM, I imagine). If I really have to nitpick I would repeat what @Taylor (Signals From Beyond) said - I also prefer when there is some leeway for the players to talk themselves out of the encounter etc. But overall this is some solid piece of content and I love it!
