I watched all 3 seasons in a row, so it was very obvious to me at which point exactly they throw away the books and turned the show into a completely and utterly NETFLIXIAN cliché. I could practically see the script writers standing up and packing their things while surrendering their position behind the desk to some "original Netflix" writers who fill every show with LGBT characters, bullies, and look-alike MCs. Ever since then I didn't feel like I was watching Anne of Green Gables any more, but just some Netflix heroine who didn't have any characteristics of her own, and would solve any problem by bonding and regrouping with her pack like any other of her kind.
I don't even start on how they just wrapped up everything on season 3 and ruined many story lines without actually finishing them, I just say that during the last few episodes I found it hard to stand the MC, who didn't possess any likable quality anymore , and was nothing more than a hypocrite and moody person.
So, if you want to see Anne Shirley just watch the first season. That's all.
