It sure had it's moments and I really liked the music and the scenes where they all had a shared experience, but for the most part nothing really happened. There was no story there. It got better in the last episodes but overall it's somewhat of a disappointment.
The scenes with Swearengen "Sweadgen" and Wu are the best.
I did not like how they chose to end the series, let's just leave it at that. One of my favorite shows nonetheless, with my favorite season being the fourth.
