3 out of 5 rating for Carrion Crown Adventure Path
I remember that the FIRST adventure was really great, one of the best 1st-Level modules I ever experienced. That level of excellence was kept for the first half of the SECOND module, "Trial of the Beast" (second part was a slog). Adventures 3, 4 and 5 were rather dull and boring in my experience. The 6th one was better, but not at the levels of the first modules.
I think that the authors divided the modules thematically (Horror Stories? So, ghosts in the first adventure, then Frankenstein, then werewolves, Chtulhu, vampires and... a Legendary Lich Lord in the end!), but that was not enough, they had to work more on the style, because I found no horror in these horror adventures.
So, if you want to taste this AP, I recommend to play the first installment, maybe a half of the second one.
