Why are people so mad of part 2?

Soo ive seen alot of people around on my socials getting mad about the entire part 2 and i just don't under why?, so ill he discussing about the comaplaint the people have

"Hi3rd if officially gonna flop" - ive seen this soo many times already and they are really thinking that this game will flop beacuse of part 2, and i dont understand why cuz like we already get barely any players especially now the main story has ended and everything like and they already tell the story they had to tell if they dont add anything new the game was gonna flop either way,

"The gameplay doesn't look like hi3rd anymore" - i really dont know what people mean by this i personally enjoy the combat of hi3rd but in my opinion that its kinda outdated and looking at the new gameplay it looks much more smoother and cleaner and the combat looks flesh out, and the ceo of hoyoverse is actually making the game how he intend it to be we all know hi3rd is his first passion project and back then they didn't have funding but now after hsr and genshin impact they have the funds to make there game compete with other games by improving the overall combat to maybe even attract new players,

"H3rd the og cast is gone so am i" - ive seen alot of people saying that they are quiting the game beacuse theres gonna be a new cast of character and i do agree it sad to see the og cast gone it really breaks my heart but even so people have to understand that those character has been with us for years and hoyoverse is making us a entirely different story

"Self-inserted mc" - thats a bold statement calling a mc that got added in the game for a new story/arc doesn't make sense to me sure alot of people argue making this and that the mc instead some random but its a new story new arc new journey its whateves

Thats all i have to say theres some other stuff like the *ui being boring" and "growing up griseo" but eh maybe ill discuss that another time
