I'm planning to finish 3 overdue series tonight:
Just did the first a moment ago, it was the second season of Free! which didn't disappoint me at all really.
EDIT: The second series I finished tonight was Sabagebu! This was as crazy as box of frogs but the pop gaming/film culture references were hilarious. I counted Resident Evil, Alien, Predator amongst others.
EDIT: Last but not last I finished Madoka Magicka finally! The rave reviews from friends kind of got my hopes up and let me down but it wasn't bad.
