oh bree ^_^
bree organized my birthday party once
uh... perhaps the community hates mices because of Penny...
I don't like Penny because I had her in my first GCN town and she looks horrifying. Not to mention that she won't leave. That doesn't mean I hate mice though.

I have a list of a few underrated villager species as well as a few villagers that are a part of the species.
Alligators: Not a single alligator villager that I dislike! I really like Alfonso because he was a really cool character in the movie and he is very friendly in the games too. Boots is also really cool and like a jock version of Alfonso, only problem is that he only appeared in the N64/GCN games but was brought back in New Leaf via Welcome amiibo though you need his amiibo card.
Elephants: A lot of people really seem to not care much about elephants. My personal favourite elephant is Margie, again because she was a really important character in the movie (and a huge part of the story which I won't spoil).
Mice: While I agree that some mice can be ugly and often or not quite frightening (I'm looking at you, Penny), there are actually some good mice such as Bree.
Anteaters: There are actually a few good anteaters though I forgot their names. Was Pango one? I can't remember. I know Cyrano is one and that's because he was in the movie as a minor character.
Pigs: Quite a lot of pigs are underrated actually, such as Lucy and Truffles (people say she looks ugly, and while she is a bit ugly I also find her pretty funny with the angry eyes and evil grin).
Gorrilas: There are quite a few good gorrilas as well such as Louie and Cesar (who yet again appeared in the movie as a minor character).
