After Season One, it really hits it's stride. Season 6 is the weakest with the addition of Bronson Pinchot, who was completely unnecessary and out of place. I also didn't like that the younger brother completely disappeared and other main characters were seen less and less. The addition of the brilliant Emily Mae Young in Season 6 as "Lily" saves the show as things were getting stale. She is a star. If only she could have joined the show a season or two earlier. The last season still finishes strong with a perfect series finale. A great watch.
