Season 5 might have sucked watching one episode a week but as a binge watcher, I thought it worked out pretty well.

The whole series ended up with a narrative arc like a novel. First season was setup. Things started to pick up in season 2, then 3 and 4 built to a huge peak, and season 5 wound it down, like Lord of the Rings after the ring is destroyed.

I can't think of any other show that has a single narrative arc like this across the whole series. At most you get an arc per season. Often not even that; e.g. the new Battlestar Galactica was a continuing story but the narrative tension was pretty even throughout, with a series of small arcs, each just a few episodes long.
