The fact that you've grown to like Cyrano and Olaf makes me happy. I wouldn't say they're cute, but for anteaters, I do like them. Especially Olaf, because he and I have the same birthday. I think people should give "ugly" villagers a chance. I wasn't really fond of Al the gorilla at first. But he ended up being one of my favorites. Beardo isn't all that appealing to look at, but my best friend wants him because of how he looks. I guess that's still judging a character based on how they look like your sister thinks of Zell and only wanting cute villagers. But sometimes certain villagers fit whatever you're going for. Back in New Leaf I wanted Limberg in my town. Mice villagers aren't appealing to most, and Limberg, well, he's at the bottom of the barrel when it comes to looks. But I didn't care. He was a villager I intended to have, even though it never happened.
People think differently, though. It's nice to have popular villagers or even cute villagers. I find an island a tad more charming when I see a villager I've never seen. Also, quite recently I wanted Biff or Rudy when Mott moved out because I needed a jock. I really thought about getting Rudy because I just think he's really cute, but I went with Biff for nostalgic reasons. Most people wouldn't think so, but I also think Biff is a cute villager.
