For the price this is hard to pass up. It is complete.
The overall story has an earth friendly (tree hugger) theme to it that works if you ask me. (Melting Polar Ice caps and all.)
The 3d and 2d is stunning for a production that is 10 years old, and still very good by todays standards.This was a first time for an anime created completely digitally. IE: All done on computers both the 3d and the flat 2d work.
That being said this could have been horrible. With the team being caught up in "new technology" it could have easily set the production staff to focus on all the wrong things.
But in fact it is very good. When I watch this takes me back a few years. The style brings back feelings sparked by other (much older) anime. Akira, Bubble Gum, Megazone 23, and MD Geist all come to mind when I watch this. That isn't to say this compares to them... just is reminiscent of that class of "classic anime" with a much newer feel.
Overall the price is so cheap and the package has enough extras that this is REALLY hard to pass up.
I bought it and would buy it again if I lost my copy.
