The West Wing (1999)

The home of the walk-and-talk. Thomas Schlamme's long tracking shots through the corridors turn policy arguments into momentum, and Martin Sheen's President Bartlet anchors an ensemble that cares far too much about everything, which is exactly the appeal. It won four consecutive Emmys for Outstanding Drama Series. Sorkin left at the end of the fourth season and John Wells took over as head writer, so the rhythm changes from season five. If you want pure Sorkin, the season four finale is a natural stopping point; the later seasons are a different, steadier show that still has plenty to offer.
