I'm very much working from memory but there was a time back in the70's when I was as happy viewing this MTM comedy as its more celebrated originator and first spin-off series, "The Mary Tyler-Moore Show" and my personal favourite "Rhoda". The few times I remember in "TMTMS", she was almost the anti-heroine, the snobbish, bitchy next door neighbour whom you wondered how even St Mary could befriend. Only occasionally did she show her human side which probably made it difficult for the show's writers to centre her as a watchable character in her Jen show.
For what it's worth, I certainly remember enjoying the show on the sporadic occasions it turned up on British television in the mid-70's. Clovis Leachman was great in the title part, her face capable of going from happy to sarcastic in the one line. I was never comfortable when her daughter got air-time with her own brand of spoilt second-hand sardonic-ism but her genial but occasionally caustic middle-aged parents and her acid-tongued grandmother Dexter made good foils for her, the latter perhaps prefiguring the similar character who stole the show years later in "The Golden Girls". It perhaps said something about the star- power of the show that the episode I remember best is the one where Tyler-Moore guest- starred, perhaps to try and boost the ratings.
Perhaps I'm remembering thus show as better than it was but I'd sure like the opportunity to see it again although its short-lived TV shelf-life makes that only a remote possibility. One thing it did have was a great bitter-sweet theme tune which arguably captured the title character's personality in one pay-off finishing line better than two full series of half- hour shows!
