OCD afflicts Girls main character Hannah, who has been in remission for the better part of a decade. When it returns, we see a full blown relapse in all its eerie "glory." Hannah's first bout officially appeared in high school. We imagine her as a neurotic over-achiever with dreams of being a writer, who went overboard, as she became out of control with her desire to be in control.
Except while the images were happy, the underlying themes were not: Hannah, Adam, Marnie and Charlie are all back to square one. Any personal gains they've made in the year that the show has depicted were erased with one single montage. It was "Girls" as "The Graduate": the characters won the battle, but lost the war.
If this were school, the girls of "Girls" would be failing. But it's life, so it's even more depressing. We're already eight episodes in to Season 2, and the girls' togetherness scores have only decreased. Hannah's suffering from OCD, Marnie is desperately following Charlie around Manhattan, Shoshanna is hooking up with doormen, and Jessa is missing.
