Raya in concept is a good movie, but it appears to be lacking substance due to editing. The animation techniques and art style of the movie are very unique and well developed in most spots, but the story is lacking, clunky, and jumps around without much explanation. The animation has an interesting combination of cartoon and real-life which caused an uncanny-valley effect and many of the techniques looked experimental, which worked in some scenes but not in others.
In regards to the story, the film was blatantly female-power oriented (but that can be attributed to the era) without having the main female leads recognize their faults. The heroine causes the climax of the film (which is bad) while the villain acts as the catalyst, but only the villain is blamed as the sole cause for the "bad stuff" and neither recognizes their faults and wrong-doings (that they have both obviously caused).
The worldbuilding was attempted at the beginning of the film, but only in one part of the world; the newly introduced animals are never shown again and there are no new animals introduced beyond the halfway point of the film.
Lastly, there were key trends that were noticeable and disappointing; one of the main characters is an obvious resemblance to Boss Baby, and not in a good way as a poor comedic foil. Also, there was an attempt at potty humor with the introduction of a flatulent beetle that was used as a throwaway gag.
This was the epitome of a good idea- a decent story, with beautiful mental imagery, but was not brought into reality well as it was torn between an epic and a children's cartoon.
