I've only run one actual session of it, which went well, but its a little early for me to say much. I have read through it and really like what I've seen, though. I'm a little sad that the traveling bits end up being so dull because I was looking forward to them. It seemed like they were trying to emphasize the "journey" part of quests that many storylines skip over.
Still, having ran a few of the early 4e modules, which were nothing more than big dungeon crawls, I'm excited to get further into this one.
