Boy people are fickle did they just want to sit in a theater watching the original tv show episode but with nicer art?
you wash your mouthnicer
Pokemon Origins proved that you could make a different story with the same "area and feel"
But if you want to tell a kanto story taking the things that made kanto unique and replacing them with generic stuff, of course people will be bothered
This is ingoring context with this movie, which surprise, is focused on the beginnings of Ash, which surprise again, took place originally during gen 1. It's not a totally unreasonable opinion to want it to be focused on the original 150 too.
You guys are so busy getting angry at perceived slights against the latter parts of the franchise that it's really weird
No you don't get it if you dont want a gen 1 story to have mega evos and z-moves you're a genwunner
