They weren’t sure there was even going to be a second season until they saw how well the first season was reciebed. The second season has many more eposobes to go. the dirst episode was 2 hrs long, the 2nd episode as well as the 3rd 4th and 5thb episoes are an hout long, and then, the fibal two episodes are each 2 hrs long. So you see, there are 7 episodes to the second season, 3 of which are 2 hrs long.
Don't get me wrong; I think it's great quality TV. But long gaps between short “seasons”, not to mention a lack of commitment to further shows, exponentially increase the likelihood I'll blow it off next time around. I've gotten sucked in and then burned too often by network programmers.
