Crap it's hard to choose out of so many... I had to say Fantasy, because it just doesn't work as anime.

Euch, Harem. Always hated it.
Pointless plot- Bleh what am I saying- No plot, always this stupid guy who has no traits at all, and cute/big boobed girls who seduce him for no reason.
I could say the same with reverse harem but still, Harem is much worse in my opinion.

Always stereotypes Homosexual relationships.

Bad ass and Violencia

Exactly what CoffeeMajesty said...

Or yaoi, and mecha

Even though I do like a few series that are actually harem, I generally dislike the predictability of the plot most harem series have.
I also dislike the sports genre because I don't like sports in general. They are just not my idea of fun.

Emo: Same.
