Hopefully Game Freak reacted to all the controversy over the S/M protagonist having a lack of emotion so I do hope they learned and will add actual expression in important scenes now.
As for my opinion on these new character designs, they are definitely a step-up from S/M. I will be playing as the female once again as per tradition, but I think she's fast becoming a new favourite protagonist design for me. Not just because of wearing cute short shorts once again, but that new hairstyle reminding me of one of my all-time fave female game protagonists which was Hilda from B/W.
