I rewatched this about a year ago. It was pretty poopy. As others have said, it's completely generic tripe played straight. I was particularly insulted at the final 5 episodes or so, which all of a sudden rammed the "plot" down your throat in a manner that I remember as outrageously unsubtle and stupid. Though, if you are still capable of turning off your brain and just mindlessly enjoying shounen CGI fights, then it's pretty fun. The last fight in particular expends a good bit on the CGI budget and ends up being pretty hype, if too short.
Chaotic Century was pretty much better in all possible ways. Did anyone watch the Zoids that came after?
