I think it's a bit too much. Too light even when distress is being shown, too much music, too broad strokes in some animations. The concept is interesting, but it is presented as a musical, which devaluates the singing itself. Also does not explain (even briefly), why you can't heal when someone in need (over-healing causing cancer or something?).
May suit kids, I guess, but looks like I am too old for this.
