That Arrested Development probably won't be having a long run is a very sad thing to me. It would be nice to see the DVD sales for it take off like they did for Family Guy and encourage the network to bring it back. They are both on the Fox Network and they have seemed very committed to AD. I guesss they do realize when they have something that is really good.
They don't always stay with a good show - as much as I can't stand Aaron Sorkin, I thought Sports Night was one of the most regrettable cancellations ever.
