There are elements to this movie that are very pretty. Many of the visuals are stunning, excellently deep textures throughout. The characters by and large good but their movements can be very strange at times.
The real problem is the murkiness of the story. A narrator would have been an excellent improvement. Without an internal monologue or narration the cat seems to be crazier than you would guess. The setting is perplexing with random elements from Spanish, Middle Eastern, and French styling with no clear rhyme or reason. Also for no clear reason a school of ghost fish come to life near the end. yep.
The voice acting was also painful. Namely Shatner's cat voice is something to truly despise. The monkey is Jamaican? Most disappointingly is that they didn't get a quality singer for the princess.
This last point sticks out because there was a lot of music in this movie. It has a charming American Indie vibe including stripped down percussion and on occasion a ukulele. But her voice fails to be either traditional or suitably indie.
Also the Ogre is inexorably dumb and useless as a villain.
