Just finished a rewatch with my wife who never really watched the show and I have to say the last two seasons were a lot better than I remember them. Michael leaving was a void that was never going to be filled, but the show was still good, although obviously not on the levels of seasons 2-5. The last couple episodes were great, letting everyone say goodbye and I still rank the finale as one of the best. Nellie still sucks, but again not as bad as I remember, but it's a small price to pay to be back in that world.
