Where to start? Character designs were not of my taste, but when I've seen them in stills the actually were half-drawn. Animation was minimal and inconsistent, which is kind of hard to succeed with this non-existent detail within the same damn episode
The BGM was erratically changing without any regard for the mood of the scene. But there were hints that there will be a plot (fix that curse thing or whatever), it's an RPG anyway
Now let me move to the bad points ... these characters are as
annoying as Naruto! They are childish, stubborn, stupid ... and have power ... very bad combination for non-teen audiences! Just reminds me of every other jerk in middle/high school.
