Is this season 2 of "Lost" again?

The episode of Lost last night reminded me of the episodes from season 2. There was a bunch of character development, but no real plot movement. It seems too late in the game to have episodes that don't move the story forward since there are only about 20 episodes left of the series. In this episode, we learned about Miles and his entire story, including a brief appearance by Naomi. It was fairly interesting with no reveals that hadn't been figured out by now. Hurley was his usual comical self. Jack, Kate, and Sawyer are on the precipice of being ratted out for their moving little Ben to the Others. At the end of the show, Dan came back on the island. Next week is a recap show and in two weeks the 100th episode will be on.
