Seriously, what part of "Go is a main character." and thus "Go does not hog screentime that is rightfully his." do you and your likes not understand? Or are you saying by equivalent that every time Ash has gotten focus at any point in this show's past, either unyieldingly or next to someone else's specifically designated episode, that Ash was hogging screentime? Seriously? This is utter ridiculous, and bordering/surpassing shameless character bashing, not to mention spreading misinformation and misconceptions.
My only issue with Go is his unrealistically miraculous success at catching Pokémon, which flies in the face of everything the anime has shown us about catching Pokémon up until this point. And I think that's one of the reasons he is getting so much hate from viewers. Really, he is not a bad character. IMHO, he actually serves as a nice contrast to Ash. Go values quality over quantity, whereas Ash is, and always has been, the opposite: he values his bonds with his Pokémon more than the number of Pokémon he has in his roster.
The only problem I have with Koharu’s development is that we already had past characters who didn’t have much interactions with Pokémon wether it be dislike (May) or fear (Lillie). It just seems like an old plot with a new coat of paint. I appreciate them fleshing our Koharu but I want her to expand more than “oh she’s not really good at/exposed to battling”.
I think Koharu is different from May and Lillie. She doesn't dislike Pokémon, and she is not afraid of them. She is just not all that interested in them, but everyone expects her to be simply because her father is a Pokémon professor. This is a classic case of people expecting a child to follow in his/her parent's footsteps, and I actually hope they expand more on this with Koharu.
Sakuragi and Koharu don't live in the lab. They have a house they go back and forth like, you know, a normal job. That means, Ash and Go are probably the only ones living there. Maybe those two assistants too but I think it's more likely it's same case as Sakuragi. Kind of weird. Though I wouldn't doubt if we get a filler where Sakuragi gives a day off to everyone and Ash and Go are in charge of taking care of the lab. Team Rocket shenanigans happens and there's a whole mess straight of those stories where the kids have to take care of the house while the adults are away just so everything go completly wrong
I believe it was stated in one of the earliest episodes that Ash and Go are staying in the dormitory at Sakuragi's lab. We know at least one of Sakuragi's assistants doesn't live at the lab, as this episode showed her arriving to work. But this is the world of Pokémon, where 10-year-olds are considered old enough to travel the world on their own. Two 10-year-olds staying in a lab dormitory by themselves isn't weird at all. Besides, it's clear Mimey has taken on the task of doing the chores.
However, it
is kind of odd that we haven't seen Go's family before now. I understand him preferring to live at the lab rather than at home, but you would think his family would have checked up on him by now.
I'm pretty sure that it's been implied a few times already in this series that Gou is more of a collector than a battler, so I don't really understand why some viewers still think that he needs to train Hibanny or any of his other Pokemon when that isn't supposed to be Gou's forte. And frankly given how much of an easy target Gou has been lately, I think that him getting stronger as a trainer would only lead to more backlash for him, regardless.
Someone else already said it, but (
hopefully) eventually Go's miraculous capture rate will decline, and he will actually have to start
battling the Pokémon he wants to catch. In that case, he will have to train Scorbunny and/or his other Pokémon.
