The only part thats a bit of a disappointment is the part where they use their real pokemon. It looks like they arte only using their main pokemon(Pikachu, Shinx, Piplup, Croagunk, Slowking and Seviper.) That means Ash's other 4 pokemon didn't appear for 4 episodes straight
I bet Ash, Dawn, Brock and Aoi are on the underdog team(Team Red) and Jessie and Conway are on Team Blue
Urgh that picture with Aoi blushing at Ash actually makes me feel ill. I don't know, I just hate pairings like that. I didn't like Anabel x Ash and I don't like this.
There's my off-topic, probably going to annoy people shipping rant out of the way.
Seeing Brock ride on Lapras is a little... eh. I would have prefered Lapras to be Ash's across-the-lake Pokemon just for old time's sake. That said, people would probably have gone on about it being foreshadowing. (Although one of my guilty pleasures is Lapras of Luxury so... I could have lived through it just to see Ash on Lapras again.)
I'm a sucker for anything that reminds me of the Orange Islands.
Obligatory laugh at Dawn riding Sharpedo.
