I'm watching it still, and liking it, although I will admit it's more for the overt intensity, almost melodrama, than anything else. It's still got a great cast and performances, but specifically it's the elevation characteristic of each episode is what REALLY draws me in each week. Things just build and build and BOOM. You're just there with it (for the most part).
I really thought Jill's friend was the one Garvey had an affair with, and that's trickery on behalf of the show, I'm sure. The only reason I like having her around as a character is that I knew girls in real life like that back in the day. Not exactly girls I wanted to be friends with, but ones who would talk off my female friends' ears, were obnoxious attention-seekers, and yet my friends would somehow be drawn to that, as useless as this person seemed to me. She's a good counter to Jill, although I know exactly what you mean.
Do you think everyone would go this nuts in society if people disappeared, or are these stories focusing on the ones who are being driven crazy by the mystery? or perhaps even those driven crazy by thinking they have answers?
