BIG THANK YOU TO +Eric Fabiaschi for his awesome review of The Lizardmen of Illzathatch!
There's something to be said for dealing with a straight forward adventure at times; sure everyone might be looking for the clever twist to your old school. The menace here is very well thought out and gives a DM an opportunity to play around with some of the older edition monsters and give his PC's a run through with all of this adventure's setting pieces and menaces a run through. Be warned this adventure isn't a cake wake or push over stupid players are going to pay with their character's lives. Another clever inclusion is the per-generated player character roster that's included. These PC's could be used as survivors of previous encounters with the adventurer's menace, or as fodder for future horrors that might still result from some of the adventure elements that have been left behind by those that cane before..
