I only watched this on you tube rather than give it a rental or even own it. That said, I did like the opening sequence which gives the complete history of Pokémon. However, after that it begins to go down hill and becomes another advanced generation episode with the same old paper-thin, immature, predictable plot, annoying characters (like Max and May), and same old third-rate pop songs from the show. I did like the animation though, and how Lucario had to understand humans, but with the inclusion of Mew, it kind of lost its "umph". I only recommend renting it to see what it is like. The third movie still ranks even with the test of time as the number one Pokémon movie
