After watching a better quality of this episode, I must say things are looking good so far.
I like the new Opening even more, how they go from silhouettes to revealing the Pokemon that were shown. Looks very interesting. And it's a first for no humans being in there I think which is pretty interesting.
Jessie's Koromori seems pretty strong, able to beat Ash's Mamepato and stop Pikachu's moves. It did lose to Mijumaru quickly though.
I think this is the first time Jessie, James, and Meowth didn't blast off again. I did like them before this all, but I must say I like them even more. It seems they still bring some humor to the show(For me anyways) and that was my only concern, so they are perfect. I hope they stay the way they are, in the sense that they don't blast off anymore and are more successful with their job. Hopefully they wont have times when they are friendly to Ash, Iris, and Dento too, I didn't mind it before but that was when they were less "evil".
The only thing I don't like about Best Wishes so far is that it's so awesome. And what I mean by that is, because it's so awesome waiting for the next episodes will drive me insane lol. Although I have no problem with that, so long as they keep up the awesomeness in Best Wishes.
