It was okay. Some theme episodes work, some don't. I think they probably should have left it to the one Britney episode. It was nice to see Puck and Santana briefly.
Not really sold on the Jake character at all.
Rachel looked REALLY sexy when she was doing her tango.
I'm wondering what the thrust of the New York storyline will be. In Glee club there have always been the milestones of sectionals, regionals and nationals. But in New York it's just basically a day in the life of Rachel. I hope they introduce some of her classmates, maybe contrast the togetherness of Glee club with the competitiveness of NYADA.
