After losing my patience with Miserable Meredith at the end of series 3, it was with relief that series 4 showed a turning point for our 'twisty and gnarly' heroine and friends.
Meredith FINALLY gets some help dealing with her past, the nurses lead a revolt against the ever-sleazy McSteamy and the relationship between McDreamy and the Chief takes and amusing turn. There are the usual intriguing patients who teach the characters meaningful lessons, mean surgeons who enjoy making life hell for our posse of students and for the first time Mer, Christina, Izzie and Alex are reponsible for their own interns.
Not to say all is fun and games - the repercussions of George and Izzie's fling is felt throughout the series, the Nazi faces some real personal challenges and uptight Christina (eventually) faces up to the fact that Burke dumped her at the altar. Oh, and Ava/Rebecca/Jane Doe re-appears, which upsets the apple-cart no end.
All things considered, I'm still addicted to Grey's and can't wait for the next series. Buy it now, snuggle up on the sofa with a blanket and some ice cream and turn your phone off. Enjoy!
