As someone who eternally been old and somewhat grumpy, I can say it looks fine. (And I've definitely liked some generations less than others). I'm mostly weirded out by the fact this time I am the one experiencing elements of the country I am most familiar with being remixed into a Pokémon game. It's very strange, though they got the patchwork countryside thing down. They scaled all their models down for X & Y, so they're probably working off the same pokémon models, just scaled down a bit less. Mind you, Let's Go was always going to be the baseline for how it looked, although less square than those maps.
