The big theme of this season is change. Everyone pretty much knew that Katherine Heigl and T.R. Knight wanted off of Grey's Anatomy, and they both got their wishes during this season. »»
Having never watched the show, I wouldn't know if this is a big deal or not. »»
The acting during this season is on par with previous seasons. The cast of this show is extremely diverse and interesting. You can't help but have an opinion on every character, good or bad, and see what happens to them. The subtractions of Kate Walsh and Isaiah Washington this season are tough, especially Washington who played an outstanding character. Kate Walsh is not missed nearly as much due to the fact that she is replaced in a round-about way by Chyler Leigh, who is Meredith's sister. There is great conflict between Meredith and Lexie and the addition of this character was fantastic. So fortunately the overall additions to the cast equal out the overall subtractions from the cast this season. »»
