The second best season in the series starts out as being just another day at the office, with the president riding his bicycle into a tree, Sam accidentally sleeping with a callgirl and political issues up to wazoo. The first season got a total of nine Emmy Awards, and they're well deserved. The script is magnificent, the cast exceptional, and the plot varies from ordinary to divine.
What makes this season so good? What makes this season one of the two I could (and do) watch over and over? Well, the cast members are still working their way into their respective characters, feeling their way on how to deal with their own acting and reacting, and the fact is, it just gets better and better from start to finish. Once you start, you can't stop. The plot is engaging enough to keep you interested from episode to episode, and then all of a sudden something happens which leaves you completely star struck. Toby's conversation with Mr. Willis and the other congressmen, the staggering (literally!) performance of Roger Rees as the Lord John Marbury, and the increasingly quick and amusing bouncing-back-and-forth comments by Sam, Toby, Josh and CJ sets the standard for all the other seasons to come.
It also sets the tone for what kind of president Bartlet's going to be. Intense, oratory and passionate, the president goes from quoting Roman emperors to saying "well, duh" in the same sentence. Toby later describes him as "the two Bartlets": one is the absent-minded professor with the "Aw, Dad" sense of humour; disarming, unthreatening, good for all time zones, and the other is the Nobel Laureate searching for salvation; lonely, frustrated, lethal, who's father never liked him because he was too smart. On the one hand a scholar, on the other hand an average Joe who can say "get your fat asses outta my White House" when he feels like it.
This thing is great, which is why it got a total of nine Emmy awards. If you haven't bought this already, do so. That's all I can say, really.
