It's a great series so far. It's definitely one of the best cybertech thrillers out there, even better than the movies IMHO, if only because it now has the time to build up the back-stories of the Section 9 cast. The various stories are well-written and weave in and out of each other - even the individual ones.
Of the first season on SAC, I have the first 6 in normal (non-DTS) DVD version and the 7th in DVD Special Edition with the Tin Case and Laughing Man T-Shirt. I also have the first 3 2nd GiG DVDs and have been following the [adult swim] airings.

btw, in Episode 11 ("Affection"), did you think that the boy could possibly be ... Batou?
