People sure seem to dislike this one, but I was pleasantly surprised. The whole scenario takes place in a cathedral, which was an interesting setting. Though the initial sneaking-in isn't particularly well done, I thought each encounter was interesting:
-An air elemental that uses fly-by attack while the PCs are stuck on a balcony-- he's hard to hit and good at hitting, and your PCs will need to use good tactics (like readying actions) to bring him down. Luckily, he doesn't do much damage, so he's unlikely to wipe them out.
-An animated window that humorously tackles a PC-- getting through his DR is tough for low level parties, but his AC and HP, again, aren't really high enough for him to be truly dangerous (unless your PCs are level 1, perhaps).
-Two goblins that use secret doors to sneak around the PCs-- it's fun for the PCs to have to deal with goblins appearing and disappearing, and the goblins are so weak that they'll go down in a hit or two, meaning the the fight is novel, but again, not truly frustrating or deadly.
-Finally, the boss, whose main goal is to delay the PCs while some NPCs are strangling to death on a gallows; he makes cool use of a feat to keep PCs from advancing. He has pretty robust stats, but since he's mostly worried about stopping them and not working at killing PCs one at a time, dealing with him should be doable (again, good tactics help).
The maps are missing some labels, which is a big problem-- check out the "product discussion" tab here for some help with that.
I do find it odd that people act like the underground tunnel the PCs aren't supposed to go in is a huge problem. I could see it being an issue in a home game where PCs are obsessed with exploring every angle, but... this is a four hour PFS game. If you hint to the PCs that they should leave it alone, they will if they're not morons.
There isn't a ton of plot here, but that seems to be the case with most of the Shadow Lodge scenarios-- there just isn't that much actual information for the PCs to uncover.
A pretty short scenario. You'll probably finish early.
