After Derek died the show was ruined. The show was successful with all of the original characters and they ruined it by getting rid of everyone. They took the happy endings away from too many people. Izzy and Denny, Mark and Lexie, Meredith and Derek, Owen and Cristina. George's life, Mark and Lexie. Cristina and Izzy were solid characters. Big mistake. Patient heartbreak was hard enough. The show should have been kinder to the cast. Meredith has had it the worst and to do that to her was awful. Shonda Rhimes is cruel in my opinion. Paying them more and keeping these characters would have been a good move. I never rewatch it past season 11. Get it off the air already.
