The Encounters setup does not do the adventure justice, but it was workable. I ran it for my local Encounters season, and everyone had a blast. Of course, we had a fairly regular group and I didn't follow the "encounters" setup of 1 event per session (we took 3 sessions just to get through the Intro). In the end I had to shotgun the party through events to finish on time, which I felt lessened the experience, but it was still really fun overall.Both MiBG and LotCS were pretty awful in the context of Encounters, especially if you ran them with the Playtest rules, which were all over the map.
Oh, and there was a playtest packet changeover near the end, IIRC, so we ignored it for the season.
