This was an excellent animated adventure. It is considered by many to be the best Pokémon movie of them all. I totally agree, although I consider "Pokémon Heroes" to be a close second. Both films have similar elements that make them great.This film has one of the more engrossing story lines in the series. Ash and the gang meet Lucario and travel to the Tree of Beginnings to find answers regarding his master Sir Aaron betraying Lucario and to find Pikachu, who had been captured by Mew.Lucario is a nicely developed character, and his relationship with Ash was very well played out. It was also nice that the Ash/Pikachu dynamic was toyed with. It was a good way to raise the steaks.Like "Heroes," there are times when this film feels reminiscent of a Miyazaki picture. The Tree of Beginnings was a very imaginative setting, and the backstory behind it is intriguing.The action and chaos taking place at the Tree of Beginnings is some of the most exciting the Pokémon series has ever done. The climax where Lucario saves the tree and sacrifices himself is not only thrilling, but also filled with pure emotion. He is then reunited with Sir Aaron, who was the hero after all.Another thing, Kidd was a pretty cool character, and "We will meet again" is another great song.A great film that deserves its praise from the Pokémon fans. This and "Heroes" are my two favorites of the series because they combine great story lines and emotion along with the fun and adventure you expect from Pokémon. This is an absolute must-see for all Pokémon fans.RATING: A

This deserves 10 stars. It was a very excellent movie, and the character development was exceptional. The plot was actually fantastic, and the way it was all put together was amazing. I was not expecting this from a Pokémon movie (after seeing the second one today), and a bonus - included one of my favourite Pokémon (Lucario). It also had an incredibly touching ending, it made me shed a tear. All my feels go out to this movie. This movie was a bit cheesy at times ("My aura is with you!"), but hey, this movie was intended for children. I've been a long-time fan of the games and cards, but this movie has won me over for the movies. 10/10, would watch again.

I was a little hesitant to watch this movie, after seeing the other Advanced Generation movies (Jirachi, Deoxys). But I'm glad I did. The opening was one of the best introductions I've ever seen to any movie, and the title was just as impressive. I was a little curious as to why the main theme (I'm Unbeatable) was postponed until twenty minutes into the movie, but it went well with that particular scene. And the plot was fascinating, albeit with holes in places. At places, the movie even made me cry--something that hasn't been done since Pokemon Heroes.Overall, an enjoyable film. Highly recommended, even to non-Pokemon fans.

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
