I'm in the process of expanding the types of anime/manga I watch/read. I have found my taste in both to differ by quite a bit. When watching anime, I prefer to watch shows that pack lots of action, while the manga I read is more geared towards comedy/romance.
I've found that my interst in certain shows becomes more developed as it goes on. I really enjoy Kekkaishi. The reason is more than just the action and battles. I enjoy watching charactors develop into differnet and, hoepfully, better people.
I'm currently up-to-date on the manga "Kimi no Iru Machi". Although it would be more common to hope the male protagonist and female lead to get back together, I find myself hoping that he stays with his current, and against-the-norm, girlfriend. I get annoyed that a more "perfect" sort of girl always ends up with the male lead.
My tastes are still developing, and as i get more and more into different things, it stays exciting all the way through.
