The problems arise because all, or at least most, of this potential disappears due to a lack of following through.
The characters reveal themselves to be pretty detestable. I said they were interesting-looking, but once they started opening their mouths, well, that's a different matter. The only ones I didn't hate or at least dislike were the ones that never really had enough airtime for me to build up a dislike for them. They were mostly flat and underdeveloped and just plain irritating, although nowhere near as irritating as the protagonists, who just seemed to be very very stupid. Jin and Toa couldn't see beyond how besotted they were with each other (which got really boring really fast), Kazuki couldn't get over his personal (and somewhat jarringly over-the-top) vendetta against Jin, and Gio took most of the series to figure out that three really does make a crowd (admittedly when realisation did eventually dawn on him he proceeded to instigate the highlight of the series by: blowing stuff up - lots of stuff.)
The animation was the other thing that really annoyed me. It was fine, there were no real problems with it - until the CG dragons came along (the CG looked very out of place amongst the otherwise perfectly fine artwork), closely followed by massively over-endowed ladies (as in serious spinal injury type bosoms).
The only thing that stood out for me above the rest was the music. It was a little generic, but I still enjoyed some of the themes.
Overall it was a bit disappointing to say the least, but if you happen to want to watch something with the single intent of picking holes in it and laughing at it, then this is right up your street.
