The mom is a ludicroulsy ugly woman

I guess they had an ugly character so they wanted an ugly actress, but what the hell...she looks like a man!
Even her dreadful looking halfman husband looks good next to her. Was she supposed to be a transgender?
No way somebody that ugly can have cute kids like those!
I think it was a very poor casting choice.
Also, not to stereotype, but usually the uglier outside the prettier inside.
Ugly people like that woman would not judge others like she does in the whole movie.
Look in the mirror and shut up, monster!
