I never read the Adventure Manga but I know enough about it to facepalm when I heard what they did with Nate. Now the idea behind Nate and Rosa are interesting: Rosa is a former Team Plasma member who was loyal to N, when Plasma fell apart her mother moved them to Aspertia Town to escape the fallout. Nate is an interpol agent doing an undercover investigation searching for Plasma members, while normally serious during his undercover work he acts more juvenile (notably flirtatious on young female suspects to get close to them until he can figure out if they're guilty or not). Okay at first, does make Nate sound a bit like a jerk especially with how he treats woman, but what really annoyed me was two things: (1) Nate couldn't just be a interpol agent, no, they made him a super agent and notably he's of hire rank than LOOKER. Come on, don't pull that BS on me! (2) By making both Nate and Rosa non-native to Aspertia Town, they wrote away the childhood relationship any would have had with Hugh which was one of the driving forces of the narrative.
I like the idea with one of them being a former Team Plasma member trying to form a new life after the collapse of Plasma, so the other I would have just kept as a normal kid who grew up in Aspertia to maintain that friendship angle with Hugh (and just to have a "black & white" them going, make them feel indifferent to Plasma to balance out Hugh's hatred for them).
Of course I've always had issues with the Special Manga, like people considering it the "ideal" Pokemon experience/adaption and some of the choices they made with the characters. I'll turn the other cheek for earlier decisions as the early games didn't really give them much of a story to work off of (though making the Indigo Plateau Elite Four a group of geocidal sociopaths is certainly... a choice...), though some recent stuff feels like they either missed the point (Team Flare are not meant to be a serious threat...) or take characters in bizarre directions (like Selene, Sun & Moon's playable girl character, is apparently this super professor in poisons, why?).
Yeah, it's controversial.
But you know, all of the game protags are literal childs that somehow dismantle criminal organizations, save the world, beat and or capture legendaries, AND become champions as soon as they leave on a journey, so I really don't see the problem with the Adventures protags.

Speaking of which, the SwSh ones are looking fairly interesting rn instead of being almost perfect like Black 2.
