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.
I get what you are daying, but it has been my impression, that Brit-TV shows, usually start their first seasons with a short trial season of about 6 episodes, If they don’t grab ratings enough, in those few shows, it gets cancelled.
rach of the first season shows of SA were 1 1/3 hrs liong,...so they totaled 6 hrs...
