Melissa goes back to school with 21 Jump Street, Michael is still tormented by Mekhi Pfifer and Torchwood: Miracle Day, Titanic sinks in 3D, Keith Olbermann gets fired (again), Chevy Chase loses his shit and perhaps his job, and we run down what's new this week at the movies, on TV, DVD, Blu-ray, Netflix, Hulu, and in Books, Music, and Theatre. Viva la revolution!
