Artistically, there is little about the movie to recommend. The animation is sub-par, the dialogue is flat and in the case of most Pokemon, nonsensical. Their language appears to consist entirely of their name or derivatives of the same. The moral seemed to be that Pokemon, while highly competitive, prefer cooperation to confrontation. A similar moral was tacked onto the end of the feature film.
Fighting is bad.
The problem with this is that neither moral is supported by the film which precedes it. The Pokemon are designed to engage in combat. At the end of the film, after the characters have realized the error of their ways, they fortuitously have their memories cleared, presumably so the Pokemon craze may continue unhampered by the insincere moral message of the film. In other words, the true message being delivered is that fighting is bad, but we're going to do it anyway. The insane popularity of Pokemon should give spiritually minded parents pause.
