Strongly agree on Mad Men & Arrested Developement.
As far as cancelled shows, the network suits are just as clueless as ever. To AD, add Pushing Daisies and Eli Stone this year. While not on the same level, they were different enough to be interesting, and something I could watch with the family.
God knows, we need room for more dancing and "reality" shows...
What's currently on that I like besides Mad Men?
