I'm a big fan of the Final Fantasy games and also of anime, so when I saw this series available on DVD I rushed out and got the first phrase. It's not a bad series, but it's not for everyone - and it's certainly not something I would recommand to most people. It has interesting characters, amazing music (some straight from the games), and some nicely done animation... But one main thing stops me from liking it, is that it seems to be aimed at kids. The voice acting is afterschool-cartoon-grade, the art direction is cutesy and immature, and the same goes for the plot, which again is cutesy, immature and thin as rice paper.
If you're after a Pokemon or Digimon type cartoon show, then this is for you. However if you're after mature Miyazaki-grade anime then look elsewhere.
