Zentrix is a great show, made by a Chinese studio in an anime style.
The story is a bit like Terminator; a princess goes back in time to prevent a supercomputer and its giant robots from taking over a fantasy world.
The animation quality is astonishing, given that it was originally released in China in 2002. It hasn't aged.
For a family show, it has amazing robots, amazing fighting and is a very action-packed, exciting and very cool sci-fi series.
The only thing is that voice acting in the English-language dub of the show is a bit tiresome.
I wonder whether watching a Japanese or Chinese dub with subtitles might be an improvement.
The show had a great website with lots of images and renderings of the characters and robots but that was closed down long ago.
About the only thing left is a blog created by the show's very talented character designer; Felix Ip:
