Exactly my opinion right here!
I think it depends in which part of the world you live in as well. I've noticed that someone in here mentioned that little boys tend to have fangasms over "cool" Pokemon like Charizard or Lucario. In western countries, people prefer the manlier sort of Pokemon. Those badasses. And thus, those are kind of overadvertised here. But in Japan, there's more of a culture for the adorable and cute. Hence why a lot of those get advertised as well, probably more so than the cool ones.
But there's just as much variety for cute Pokemon as there are other types. it's just that those cute ones, due to Pokemon being a Japanese franchise and them being more marketable, receive the most attention. Pikachu is favored rather than the still cute, yet badass Raichu.
Basically, I don't think there's too many cute Pokemon. I just think they're overadvertised and it makes it difficult to remember that we have plenty of beasts in here. As well as Pokemon that are both cute and cool. (Like Raichu.) Those tend to be my favorites.
