The medical drama's second season could be diagnosed as bipolar; in other words, it got much worse and much better at the same time. Whiny, self-involved surgical intern Meredith Grey (Ellen Pompeo), arguably the weakest spot in the otherwise likeable ensemble, had already left viewers annoyed. But season two, in which Meredith coped with being dumped by her married McDreamy (a.k.a. neurosurgeon Derek, a.k.a. Patrick Dempsey) by excessive drinking, sleeping around, gazing like a sad puppy and--unforgivable!--breaking the heart of longtime admirer/friend George (the cuddly T.R. Knight), could have alienated audiences for good. (Seriously, sometimes you want to shake the girl and feed her some cookies.) Thankfully, what Meredith's storyline threatened to derail was held together by some emotional episodes, including "Into You Like a Train," in which a pair of strangers are impaled together on a metal pole, and "Much Too Much," featuring a mother's quintuplets in critical condition. But the standout show that turned Grey's Anatomy into a television force came with the January 2006 post-Super Bowl episode, a two-parter involving a "code black" lockdown when a live bomb is housed inside a patient. (6 Disc) Production Year: 2006 Starring: Ellen Pompeo ; Sandra Oh ; Katherine Heigl ; Justin Chambers ; T. R. Knight
