Whilst being seen as the beginning of the end as such, season 9 is still in no way inferior television. It begins very fast paced, and you actually feel sorry for Romano, who shines this season as a well acted but also very funny character. Abby's family problems are once again a major part of the season, no bad thing as Sally Field is excellent as usual. Mekhi Phifer really fits in well, and I have to admit that Carter's acting skill has definitely improved. To the point where I enjoyed his performances.
And I strangely like Susan Lewis. Her latter storyline is a bit weird, but overall she was very good. And there was a fire this season, at Doc Magoo's, ensuring my 'one fire a season' theory remains in place.
I suggest you buy it. No real extras, except for deleted scenes, but regardless, buy it!
