I had the audio in Japanese only, so I had no idea what was being said. Personally I don't like it when the voices of Pokémon are spoken by humans (and this is what they did here). Sure, in an all-Pokémon episode it is a great help when explaining the story, but in the main TV show they've managed without it just fine, bringing Meowth in to explain things if need be.
The story was simple: Azumarill is coming to a Pokémon festival, but gets kidnapped by a Skarmory on the way there. A rescue mission is sent out to get back their signing star, and they face off against Sharpedo and Aggron.
The art and sound were not in the same level as in the TV show or movies, but managed to bring the story to life nicely.
