Lena Dunham's divisive, much-talked about and (by this writer's measure) pretty damn great HBO series "Girls" returns for a second season on Sunday, January 13 at 9pm, followed by the second season premiere of Laura Dern and Mike White's "Enlightened" at 9:30pm.

We last left Hannah Horvath (Dunham) eating cake on the beach alone after her friend Jessa's (Jemima Kirke) spontaneous marriage and her own serious fight with boyfriend Adam (Adam Driver). Will Hannah patch things up with her oddball love and finally write the book that marks her as a, if not the, voice of a generation? Will her moving in with her now gay ex Elijah (Andrew Rannells) end in disaster? Will the introduction of Donald Glover provide an adequate response to those who criticized the series for its lack of diversity? Check out the trailer below... and find out.
