I started wacthing it last year and it's becoming more and more epic! It has some improvements from previous seasons.
-Ash is not 10 anymore (he's confirmed to be 16 year old)
-He probably has his best team ever, every mon he has is fully evolved.
-He sort of has a love interest now, Serena (one of the playable characters in the XY games)
-Storytelling is more mature now, not that extremely childish it was in BW.
-He has a Zygarde on his group, A FREAKING LEGENDARY
-He is confirmed to reach the finals in the Kalos League THAT STARTS NEXT WEEK!
ALSO, ASH GRENINJA!!!!!!
