So I know I said I wasn't going to move on to season 4. But evidently I am weak.
And what got me in this case was my soft spot for groundbreaking TV (elderly leading ladies talking of and having sex, Bechdel-test passed with colours so flying they are actually a rainbow + spot-on Marta Kauffman-esque dialogue).
And it did look up after season three, albeit not to season one-heights. Still; fun TV!
