That said this is a show predominantly for young children so it's not the most crazy story line ever.

Unlike the original, the pacing of the story has ramped but not because the over arching storyline was complicated, but rather poor pacing of character growth. Watching the Reloaded special episode (23 in Orion), it was awesome to see some of the old strange designs ironed out for past characters.
It's not perfect, but it is most certainly quality. In terms of art style, the new series has it in spades. This is a twofer review (aka Letter of Complaints) for Aries and Orion.
