Loved it. Yes, it was a bit different, but this is a "filler season" for the upcoming "rumored" movie. Either way, it did take a bit to take off but once it did, it was impossible to stop. They did a great job bringing all ther story lines together as it rolled on. Is it as good as the first 3 seasons? Of course not. But it was very good and the best thing on TV right now thats for sure.

No one else noticed that all of the plotlines never got resolved? What happened to Lucille 2 on the stairs? What about Fakeblock? The Wall? The movie? This season was a chance to fill us in of the last 8 years and to segway to a movie/new season. They know what they are doing.
