Have you seen it? All I knew about it going in was that the events unfolded in real time over 24 hours/episodes. Sounds like a concept that could go either way. An awful lot of activity would have to happen in that time in order for it to be interesting. We were immediately hooked. It drew us right in and we are already working on the 3rd season.
I love this show and even more I love Netflix streaming instantly. Whenever I'm not feeling well, which is frequently, I can always find something great to distract me on Netflix. Last year we got one of those Roku boxes so we could watch the netflix stuff on our TV. We have gotten so much use out it that it was more than worth the price.
Perhaps when our DVD player gives out sometime in the future we'll get a blue ray player and just use that to get our Netflix stuff, but for now we're super happy with Roku. It has been a wonderful alternative to expensive cable channels.
