What's Good:
- Lack of humorous side characters
- Fantastically imaginative settings and characters
- Unusual color palette (dark hues, greens, oranges)
- Very good voice cast
- Adult animation without nudity, cursing or other objectionable material
- Exquisite animation and attention to detail
What's Not So Good:
- Woefully short running time doesn't allow for true character development or depth of story
- Lack of anything "there" under the story proper; essentially a mash up of stories we've seen before
- No BAM, heart pounding moments like there should be
- No "heart" to get the audience emotionally involved with the story; characters appear and disappear to serve the story
Verdict: For adults--see it if you like animation. For kids--skip it.
