Now that Chaos Dragon is over I'll be sure to tell the truth about this series.
Chaos Dragon is a very interesting series not because it's good or unique but because it's hard to predict how it could get worse and worse each episode.
But since you could go on for hours about how terrible it was I'll just make a pro's and con's list.
Pro's : The concept itself was interesting and
Some of the less important main characters were fairly good characters.
Con's: Horrible writing, terrible lead character, barely
any effort put into the series, poor execution, nothing memorable from it's soundtrack, crying 12 year old protagonist, terrible animation most of the time, terrible character development, terrible pacing, terrible dragon designs, and plenty of other things.
But long story short Chaos Dragon isn't the worse anime ever but it's definitely close. I'm trying to think of a reason to recommend people to watch it but it's only something I recommend to people who want something to watch to learn how not to make a pathetic series.
