I watched the show faithfully in the beginning and drifted away from it when it became unfocused, then I watched the last several episodes up to the end. I would say I found the Clare (or rather the actress) cute, but her character was odious and repulsive. Between the drug use and the bed-hopping and her over-the-top psychotic rants against Republicans that only a Stalinist college prof could love, it was very hard to sympathize with her in the least (and it extended to all the characters). I thought her "death" was unintentionally humorous. It's doubtful that someone with her lifestyle and rabid inner hatred would live to be 102 (well, that is unless that masochistic (masochistic for wanting to be with her !) Republican lawyer converted her away from the dark side - quite a tall order). But then, as they say, it's just a tv show.
It is only a show.
