I can't say I'm disappointed, because I really enjoyed this 2nd season, however, the story took a turn I wasn't really expecting. Instead of focusing on the (supposedly) main theme of the series, which is Bell and his adventures in the dungeon, while he levels up and becomes stronger, they chose to put everything along those lines in 3rd plan and focus on the story. It's not bad in my opinion, however, I was expecting more badass dungeon fighting scenes. Just to clarify, among all the 12 episodes, if I'm not mistaken, there were only 3 or 4 dungeon fight scenes, and none was evenclose to specially enjoyable or emotional in any way. Still a good anime though.
