Caution: potential spoilers.
This is the 11th movie based on the Pokémon TV series. It also continues a trilogy which began with the 10th movie and concludes with the 12th movie.
It begins with a cute little pokemon called Shaymin getting caught up in a battle between deity pokemon Giratina and Dialga. Giratina drags Dialga (and unwittingly, Shaymin) through a portal into the "Reverse World." Because of Shaymin's actions, Dialga manages to escape back to the "real world," and because of Dialga's actions, Giratina is no longer able to move between the two worlds.
Soon after, the dusty and beat-up Shaymin is found by Ash, Dawn, and Brock. They're surprised to find that the pokemon can communicate with them via telepathy. After they take it to a Pokemon Center to be treated by Nurse Joy, Shaymin wants them to help it find a flower garden. But before they get far, Team Rocket shows up to try to steal Shaymin. Jessie, James, Meowth, Shaymin, Ash and Dawn (and their pokemon) end up getting sucked into the Reverse World, where Ash, Dawn, and Shaymin meet a scientist named Newton Graceland, who's been researching that world for several years, and explains the place to them. It's kind of complicated, but basically the Reverse World and the real world support each other, and when there are certain disturbances of time and space in the real world, it creates poisonous clouds in Reverse World. A great deal of this happened during the battle between Dialga and Palkia in the previous movie, which is why Giratina (the only pokemon in Reverse World, and its guardian) was mad at those deity pokemon, and sought revenge.
Eventually our heroes manage to return to the real world (though Team Rocket get left behind, for the time being). Throughout the movie so far, events have been watched by a mysterious man with a flying battleship, who turns out to be Zero, Newton's former assistant. He controls a swarm of Magnemite, and attack our heroes, as he wants to capture Shaymin. But they escape, and continue making their way toward the flower garden. But there will be more battles against Zero, more trips to the Reverse World, and more encounters with Giratina. Eventually we learn what Zero's motives are, and he must be stopped. But that's all I want to say about the plot, I guess.
Well... the story was kind of convoluted and I wasn't wild about it. But the animation was pretty good, and I liked Shaymin, definitely a cute and cool and funny pokemon. Not sure what else to say....
