Lionel. I don't hate him. It's actually really cute when he sings, and I like his house and how it fits with my island's aesthetic. He was my mandatory campsite move in and I just want him to leave.
I feel similar about Anicotti. She's cute and I like her house, but I have two other peppy villagers. I feel like she's more like a tourist in my town than an actual part of it. Fortunately, she asked to move today.
I don't hate any of my current villagers in my town however I do hate Quillson because he wouldn't move and I was forced to move him in because of your forced 6th villager move in from the campsite which sucked!
I don't really hate any Villager in general and like everyone living on my Island at the moment, but when they ask, I will let Kidd, Reneigh and Walker move out naturally. Kidd because I had him in NL for the longest time and am hunting for Pietro as my smug and the other two because I have Sherb and Deirdre and just like them more.
A very unappealing villager that doesn't live in my town is Diva though. I just can't stand her face and she randomly moved on top of my beautiful flower garden in NL! I am glad I haven't encountered her so far, not even on a mysterious Island.
