The Good:
* The animation was great
* The colours (omg, the colours!). Reminds me of Coco
* The songs were well sung and produced
* The characters were fun and believable

The Bad:
* The Story was very "meh" (but thats to be expected from a kids movie)
* The main principles of the story [spoiler](loneliness, loss of a parent, replacement of a parent)[/spoiler] felt shoe horned in.

Best Part:
[spoiler]The start of the movie when the mom becomes ill and... y'know. That hit me in the feels. Even though it feels like a ripoff of Up[/spoiler]

Overall I thought the animation was top notch (which should come as no surprise since the animation company used to work for DreamWorks) but the story was a little lacking. If they spend a little more money on decent writers they could really could go far. Looking forward to seeing what they make in the future.
