Ted,
I agree with you. The first was good, they just keep getting better and better.
Barnes and Noble had them on sale last week for buy one, get one half price. I do not know if it is over this week, or not. They were on an endcap near the sci-fi section.
The TV series is good, as well. It is one of my Wife and I's favorite shows. I rather like how it follows Battlestar on Sunday nights, so we get a good 2 hours of quality TV in.
