The thing I liked was how it built up. It starts really slow. There are plotlines which are seemingly forgotten. Characters you don't think you'll see again. Then it starts picking up speed until a much bigger picture of what the show is about starts forming. The last four episodes in the fifth and final season explain everything that was left hanging and feature pretty much every character in the show. I think there's like 75-80 characters involved in the finals.
Hmm, that does sound cool. I definitely do like that sort of style (where things build up over time). okay, you've single-handedly convinced me to give it another try.
