4. Josh/Donna Relationship
One of the best and most interesting story arcs that continued throughout all seven series of The West Wing was the will they wont they? between Josh and Donna. This idea is hardly revolutionary; in fact its hard to find a TV series that doesn't include at least one arc of this variety. However too few manage to make these story-lines feel as natural as Sorkin does here. Most will they, wont they? story-lines feel somewhat forced, casing example being the relationship between Dr. Cuddy and House, which to me never felt quite right. There are no dramatic marquee moments; instead it is a relationship that develops slowly over time. It develops so naturally that you barely notice, a refreshing change of pace from the in your face romance story lines that litter our screens today.
