Pokemon fans will love the Legendary lore, but there isn't much else to love in this movie. It's far too short for the viewer to get emotionally attached to any of the characters, so the emotional scenes at the end didn't pack much of a punch.
The best part of the movie was the 2D animation, which was vastly improved over the series, as expected for the movies. However, even that looked fairly poor whenever it interacted with the background or with the odd 3D animation. The worst though was the terribly written villain. His motives are extremely short sighted and inconsistent. His Dark Balls are way too overpowered and ruin the universe's balance. And I don't know why he can hold his breath for 5+ minutes, or why he would even do that in the first place.
