I quite liked gen 7. Ignoring nostalgia and looking at it as unbiased as I possibly can, I honestly think it's my favorite generation. I loved a lot of the pokemon, the characters and story were great, region was pretty good, and it probably had the best features out of any pokemon game. I agree trials were a bit lackluster, and I kind of wish there were actual bosses aside from just the totem pokemon, as it would allow for a lot more type variety and interesting battles imo.
Ultra sun and Ultra moon were also great, easily better then S/M. I did find the beginning slightly boring, but it's the same for any third version.
The anime is also good. Idk what you're talking about saying it's bad, I don't watch it myself but I know TONS of people who enjoy it.
And there's no "bias" against Kalos. They simply weren't satisfied with third version sales at the time, and chose to do ORAS instead.
And Sun and moon have sold amazingly, I believe they're currently the best selling aside from gen 1? So it's certainly not a failure in that aspect either.
And I suppose I should address the cutscenes... I do agree not having a skip button is a bad idea, but honestly it's kinda normal if you play a lot of JRPGs, so I didn't really mind. I also think they did a pretty decent job hyping up the games. Granted, before gen 7 I wasn't super involved in the online pokemon community and didn't keep up a ton, but I've never been more hyped for a game then I was for USUM.
