Not really.
In fact, I totally disagree.
The animations are quality, but I think the stories, such as they are, are pretty-basic, cliched and massively stereotypical, especially in the case of the black characters.
The womens' body shapes are totally outlandish and unrealistic, imo.
I perfer someone like Pamela, who at least looks like a real woman.
Personally, I think the stories would be much-more believable and therefore more immersive, if the characters were a bit less exaggerrated.
And yeah, you're right, we do need variety.
All the other girls have huge balloon tits, so that's why we need new characters like Rachel and Kelly.
Know what I mean, Pal?
