Pretty pissed that the show had to end at all and the way this season went was pretty chicken shit from the get go. While I enjoyed the show I think Sorkin fucked up royally with how the show was written. Far too much focus on major news events and then he really started to destroy the show's credibility with the fabricated Genoa story etc. There were ways he could have handled each of the issues in this story line in a far better manner.
It was an enjoyable show but it felt like he took a giant dump on it in the middle of it.
I enjoyed the show, sorry to see it end. HBO did no advertising for the final season, I saw no attempt to try to hype it at all. I thought that was odd.
