Glee’s season premiere is a two-part episode chockablock with Beatles covers — fourteen in all. That’s a lot of Beatles covers, Glee! But then, the show is not known for its restraint. In “Love, Love, Love,” which airs September 26, Kurt and Blaine are trying to figure out their relationship, and the following week in “Tina in the Sky With Diamonds,” everyone else is trying to figure out why Tina is the most radically underdeveloped of all the original characters. You deserve better, Tina.
