The beginning season were amazing!! Great actors with interesting storylines, it had the perfect amount of humor and heart to go along with the brutal cases brought into the hospital. But then it started to lose it's heart, characters became extremely annoying, and the personal issues of the characters became exhausting as they never seemed to change. Grey's Anatomy had a great cast to start with, then they took those characters and slowly made them unbearable to stand. While eventually getting rid of some of the best actors on the show to replace them with people who you will not be able to tolerate for very long. I wish this show would focus more on the medicine aspect and less on the personal lives of the doctors. It would be nice if they would clean up the cast and get better actors with better storylines or just end the show! 15 seasons is a bit much.
