I think you can learn a lot about a person based on what they read or watch. Going by the latter, I hope to share what type of Anime interests me.
My pet hates: big breasted women in anime who throw things at/and punch men for almost no reason, especially if it's their own fault. Equally, I hate it when an amazing plot line keeps getting interupted by a pervy hero's thoughts and his need to lift up skirts.
I avoid harem and magical girls like the plague (they're a favourite genre of my sister's though, so I tend to watch whatever it is she recommends. Note: I have seen a few shockingly cringy - my opinion - anime's because of this). And, strangely enough coming from a female, I mostly dislike any anime that has a leading female character. It just doesn't work for me.
I normally watch the fantastical, such as sci-fi and fantasy, though I do love a good sports anime too! More often than not, my preferences lean towards darker anime.
Don't get me wrong, there are some fabulous school girly-girly romances, and intriguingly real slice-of-life's, but they are no means my staple anime diet.
And I need depth galore, wanting to know exactly what makes characters tick.
Most of all, I love giving them a chance as I realise it often takes more than five episodes to build up a solid plot or character story line. So I never, ever, drop an anime I begin - no matter how bad it is.
