To put this season in context, the preceding season 8 is not regarded very highly, and rightly so. Whereas seasons 1-7 (particularly the first 4 seasons) are probably as high a standard, and as consistently funny, as any comedy ever made, the loss of the dynamic between Niles and Daphne meant season 8 lacked the spark of previous years.
So, how does Frasier recover it`s first weak season? Definitely, there are some seriously funny episodes in season 9. "Bla-z-boy" is one of the strongest episodes of the entire run, never mind this season. The tension between Martin and Frasier is wonderful, as Frasier can`t accept the fact his longest successful relationship is the one with his father. Similar tensions are showcased in "Room Full Of Heroes", but this time it`s Niles who offends Martin. A personal favourite episode is "Wheels of Fortune", a brilliantly cast Michael Keaton as Lilith`s half-brother Blaine, who plays on Frasier`s good-natured side with the perfect scam. Watching Frasier and Martin catching a cricket that has sneaked into the apartment in "The First Temptation of Daphne" is great; as always, my favourite moments are dialogue between Grammar, Hyde-Pierce and Mahoney.
Low points - I don`t know what others think of Millicent Martin as Daphne`s mother, but I always found her incredibly annoying! And she is in too many episodes! New characters weren`t needed in Frasier, the original half-a-dozen were strong enough to carry things on...one massive exception is the superb Cam Winston! Another development that was definitely not needed was a bizarre development between Frasier and Roz in "The Guilt-Trippers". Especially when viewed retrospectively, considering Roz`s reluctance to leave Frasier`s side in season 10/11, this episode comes a little out of the blue for my tastes. Like most fans, I love Roz, but she has a literally rubbish storyline throughout the series, as she dates a garbage-man. Considering that Roz would date anything in the first few series, it doesn`t quite feel right that she would be so superficial as to question whether she should date someone who doesn`t also "work in an office".
As always, the episodes with top-class banter between Frasier, Niles and Martin are the strongest, and there are enough to save the series. 4 stars is the bare minimum...some great episodes, but probably a few too many that seem to be filler. Better than season 8 though!
