I mean, seriously, I really like Serena, Clemont, and Bonnie. Ash's Pokemon, especially Greninja was really cool, but then I had to spoil myself, WTF?!! Anime Department, you made Ash's best Pokemon in this region to be released?!!! NO, I can understand Goodra but why Greninja?!! He could've stay for the Sun and Moon series as backup or stay with the other Pokemon in Oak's Lab (Imagine Ash-Greninja facing Charizard, who was Ash's best at the time)
And now I spoiled myself of seeing Serena finally has the courage to kiss Ash (when I found out about this, I wasn't sure if this was play out but then Serena's personality was very likable), she should've stay for the next adventure instead of training for Kalos Queen (but then again Sun and Moon is going to defeat that purpose because the series is going to be totally different than the previous season since Ash has to go to school (Really?!) and there are no gyms).
