On the whole I liked it.
The new normal pokemon were awesome, there seems to a huge open area with controllable camera, pokemon in the overworld (while not getting rid of random encounters).
Dynamax is just stupid. How about, just not have a stupid gimmick? It was megas in gen 6, z-moves in gen 7 and this now.
Megas were at least nice.
We got new temporary evolutions (could be definitive, give'em numbers!) and with them some really cool designs.
Also Charizard was finally able to become a dragon-type, which was so damn long overdue haha.
