How about beeing more specific on what you hated on the gens you didnt like, Then we can tell you if its the same or not.
The game is a pokemon game with 3D graphics, and includes good poekmon training tools if you want to go pro that dont involve having to level a pokémon from sratch. You can pool your EV's however you want. If you dont care about that, there a bunch of cool pokémon.
I cant comment on the story yet because i have been enjoying too much getting lots of pokémon and using the GTS to trade pokémon so i have the ones i like early. I have charmander, squirtle and bulbasaur and i only have 1 badge. Gen 2 starters dont seem to be in the game, sadly for you.
Theres also alot less grinding required. I was playing the game like usual and my pokemon overleveled and no longer obey my commands so i had to change to a team B. Thats me though, i was on every patch of grass trying to capture all new pokemon i see. It seems you dont need to grind at all on this one.
