This 7-Disc volume (the second season or "gig"), based on Masamune Shirow's graphic novels, is completely worthwhile, full of interesting plots, ideologies, characters, action, popular and provocative philosophy, and brilliant animation. It is intersting and impressive in MANY ways, and is a very good price for this release version. It contains 7 DVDs and is 26 episodes in total. I highly recommend it.
