Am sort of amazed at all the five stars....I enjoyed the first two seasons and then season 3 really seemed bizarre and season 4 even worse. I was glad it was over. It started getting repetitive and sort of pointless. Zoe Hart did not ring true in that character. A trained surgeon who is willing to basically do more or less nothing on a daily basis? Nope never known an MD willing to do that. She really changed in seasons 3 and 4. Two stars is all I can give this show.
