Some might not agree with me on this, but I'm ready to call Wakfu a much more mature show than it's advertised to be and I'll tell you why.
Technically, Wakfu is a French Saturday morning cartoon, aimed especially at kids 8-10. The characters a likeable, the animation is absolutely gorgeous and the action is pretty good. The plot seems interesting, but nothing really groundbreaking...UNTIL mid-season kicks in.
From that point on, things immediately seem to escalate in a rate previously unimagined, culminating in one of the darkest last few episodes I've ever seen in such a cartoon. Nox, the main villain of the season is nowhere near the usual two-dimensional villains, but has so much depth and inherent tragedy to his story(see the Noximillien special) that I think is quite rare.
If anyone else had seen at least the first season, I'm pretty sure you'll agree that it's very much above a standard cartoon level.
