Pokémon franchise has been long known for making two to three versions of their games, adding small changes to make each different yet similar, but I think this is the first time with a movie. Nice idea, although I think it's... not worth it, really. I first watched the "Zekrom version"; Ash and friends, as usual, are traveling, and meet a group of friends after helping a couple Deerling out of danger. They get more than they bargained for when their new friends, who are part of the People of the Vale, hope to restore their old, now destroyed home to its former glory. Much as Ilove Pokémon, I have to say this was from the weaker end. The story just didn't have its usual drive, and the main event/danger didn't seem that great - or rather, it was hard to see how a good person could make such bad choices and not see it happening.
Victini had a big part in the story, with its sad past and Ash's determination to help the lonely Pokémon.
The other legendary Pokémon, Reshiram and Zekrom, were sadly left to the shadows. They didn't have that great of an impact, sadly, on the story, and weren't used well enough. I would have loved to see so much more of them, in more creative ways.
Decent story, great art as usual, but a bit of a let down. Perhaps they should have pooled their efforts into honing the story and giving it a bit more edge instead of splitting it in two.
