I agree with CommonOddity.
The overall product is great, but the lip syncing is completely off and the animation isn't "fluid." I can tell that it took an enormous amount of work for each scene, but that's just it. I can tell where the scene breaks were, and I can tell which parts took longer to animate because certain parts aren't as clean as others. There's some spots where there's straight up frame skips.
Art is great, concept is solid (although cliche), the keyframes are great but the animation itself needs work.
4/5 because it's a fantastic product that needs polishing.
