Yeah villagers like Ankha and Diana are some I have left without a second thought while touring. I can see why others like them but they are not for me at all. The looks are what sets villagers apart so that's pretty much all we can base our opinions of them on and we all have different tastes.
I love a whole bunch of villagers that others dislike (Chadder is great!) and I can see why people don't care for them. It's all good tho as long as no one goes into hyperbole mode. Every single villager has fans for one reason or another and that's fun and makes Animal Crossing super cool (except for Barold, that's not fun and cool, stop liking him).
Yeah, and I won't knock anyone for liking or disliking certain visual design elements lol. Like I know you don't like Kyle because of his eyes, while I think Kyle's eyes are absolutely adorable. But tastes are tastes.
There are certain villagers that, while not offensive stereotypes like Barold or arguably Deirdre (even if it might be an inadvertent one), I think have elements to them that are just not good design. Beardo I think is one of the biggest offenders because that fuzz on his stomach looks like he's displaying his pubes. Or basically anyone that has that puke green/yellow colour palette, I have no idea what they thought when picking those lol.
