Speaking about May and Dawn yes i like them,both of this girls have their qualities and i like the way they are making progress,like May who had great development over the series,but Misty will always be my favorite character.She has great character and personality,interesting development and pokemon,its quite unique(like her goal) and i would definitely like her being part of this show again(though this isnt very promising).
Hmm Ambipom,yep that was definitely one rather unpredictable and partially unfavorable thing.Leaving because of ping pong,lol.At least writers could provided better excuse if he had to leave,but oh well its no big deal.And this doesnt mean necessarily bad thing,who knows what are writers plans with him in future.
