(Full review TBD)
I have to say this though, when El Primero was saying about his body parts being instruments. When he did his over dramatic deep breath before saying "buttocks," I covered my eyes because I knew he would say something relatable to that.
From an animation perspective I give it a fail as well. The bright colors of the animation don't serve the setting or the quaint time of the setting well at all. Why is that all 3-d animation has taken on the same style? The motley crew of bulls and hedgehogs (gag) make the story too farcical.
For younger audiences, this will simultaneously appeal to both the fun and serious sides of their ever-growing minds.
