Wow, some of the other comments are rather harsh. While I agree that this Britcom is neither a Seinfeld nor an AbFab, I think it is notable.
Most notable is the fact that the series is a good, honest representation of Generation X (and, no, not as defined by the media or corporate world, the real GenX).
On the one hand you have the main character, Louise, a craftswoman/artist, struggling to make ends meet. On the other, in contrast, you have Carla, a Banker on the way up the corporate ladder. The two, friends since childhood, remain close, despite their very different career choices and financial circumstances. The relationship, and related details, allows one a view into what was actually a very anarchical time.
Louise is struggling financially, and career-wise, and is usually either depressed or stunned by having stumbled upon yet another Mr. Wrong. And to rub salt into the wounds is the hovering presence of Louise's mother, a therapist with a lifestyle worthy of color-supplement coverage. She is the archetypal boomer, or pre-boomer, full of self-importance and a sense of entitlement that only having lived through the good time cans bestow.
Carla is nothing but supportive, Louise's mother endlessly irritating, and Louise charming in her frustration and bemusement. Additional characters - usually men who spend some time in the lives of the three woman - provide additional laughs and insight. And, although this is obviously a show by\about\for women, the male characters are three-dimensional.
The nineties may very well have been the last decade with any real substance, and this series is an interesting artifact of that time.
