Just curious - this show was recently recommended to me ("OMG this show is so good, I can't believe you're not watching" ) but I haven't seen any of the previous seasons. I was told that was OK, I can just jump in, but I'm kinda obsessive about starting from the beginning. Is this one really ok to just start without having seen the earlier seasons? If I do, is there anything I should know before diving in? I did DVR the first epi last night, so......thanks for any advice or info!
