Plot based on an animated series/manga. The special effects are decent, considering how difficult it is to translate magical movements into reality. In the animated series, everything is fast-paced, but that's not possible in the film, so it's slightly slowed down. However, the scenery is beautiful, and the animals are almost perfectly drawn.
Is that all? Just two drawbacks?
In my opinion, the only drawback is that there isn't enough time to convey the entire story. If a person is not familiar with the source material, it will be difficult for them to understand the plot. Everything else is minor.
