I really enjoyed this episode. It was so refreshing to see an episode that didn't revolve around Finn and Rachel or even about Will Schuester's love life. If you're tired of seeing the same plot over and over again this episode, you're really going to enjoy this episode because (as someone has mentioned before) it has more to do with the rest of the character's develop: their lives, secrets and wishes. I think this is the best episode (after the pilot) so far... I personally think that "artie" has a far better voice than Finn and because of that I really liked to see him taking the wheel (pun intended) and nailing those 2 songs. In conclusion, this is the best episode to make you care about the rest of the cast and think that there's a lot more in Glee. I'd only like to see more developed story lines, but I guess that's part of the appeal for a lot of people: not intricate season-long story lines.
