Last year I went and rewatched the entire show and I think I enjoyed it more than I did the first time. When it was airing I found the middle couple of seasons boring, but I actually enjoyed them all right the way through. Being able to watch them one after the other with no breaks or wait periods really highlighted just how incredible the character development on this show really was. When I was able to see it all more clearly like that, the ending didn't bother me as much.
I was actually scrolling through the forum looking to see if there would be a LOST mafia game going.
