Hmm..I'd go for anything as long as it's got a good story and neat graphics. And good characters. I'd
often catch myself reading/watching a series because the characters kept me into it, even when the plot was struggling
along.
..like when I read Akuma de Sourou for Takeru and his friends, but hated Kayano with all my heart.
As for genres...mostly shounen stuff. Action, adventure, fantasy/magic, historical...I guess. I don't really like
series with girls as main characters, I found they tend to be too whiny and relying on the supporting male characters
who also happen to be their crushes *sigh* So I usually watch/read series with a cast of more male characters than
female ones. It's entertaining, especially because I'm a yaoi fan.
