People hate Patty?

Was very surprised to find out that Patty is mostly hated by the fanbase. I'm aware that she wasn't in the original version of the game and to old players she probably feels super tacked on, but I didn't really have an issue with her? I thought she was fun and I liked her story even though unlocking the full backstory is VERY stupid. But to be fair I'm also one of like 6 people who likes Anise from Abyss so maybe I just have a high tolerance for annoying kid characters.
