The second-season finale of “Girls” is upon us, on Sunday at 9 p.m. In a way, that’s lightning fast, especially for cable TV, which tends to be Scroogey when doling out episodes. Lena Dunham’s HBO series was launched less than a year ago, on April 15, 2012, and we’re already about to see No. 20. That’s like a cable episode avalanche.
At the same time, “Girls” feels like a veteran TV series. Since its premiere, the New York-set comedy has won five Emmy nominations and inspired what seems like a decade’s worth of close analysis, hot debate, spiky parodies, and passionate love and hate and loving-to-hate. It has struck a cultural nerve, intentionally or not, raising issues and hackles and serving as a springboard for Big Statements by older writers hungry to define people in their mid-20s. “Girls” has been accused of characterizing a lost generation, of celebrating a shallow generation, and of not accurately representing a generation at all.
