The only reason I keep HBO is for "Curb Your Enthusiasm".
I am keeping HBO around hoping they'll do another "From the Earth to the Moon" or "Band of Brothers" type series, supposedly they have some related mini-series in the works (rumor is they are doing a longer one dealing with fighting in the Pacific during WWII, as well as an USAAF one). Some of the people involved with "Band of Brothers" want to do a Korean War mini-series because nobody has ever really done one, and even the movies about that era were pretty poor. I know some background work was done.
The most interesting show in the BoB series was the last show, where they talked at length to the veterans and their families, went into detail about what happened to them after the war, etc. The Snippets at the end of each show with the veterans were great, but the last show was amazing. I had read the original book and to see the entire mini-series on the screen and the way it was done, was just incredible.
