You should try. It has many genres that are not simply for kids. For example, you can have romance and slice of life too, not just guys fighting and throwing glowing stuff at each other (which is more or less a stereotype in the way a lot of adults think of it). There is also comedy and whatnot. Just don't go for the English dubbed. IMO dubs are terrible (English or not), they sometimes even change what they are really saying for something completely different. Which is why sometimes when I buy DVDs I buy them directly from Japan. Original languages are best for everything

. For example, if I watch a French movie I watch it in French, not in English.
slice of life - a realistic representation of everyday experience in a movie, play, or book.
The romance that is combined with slice of life, I find it more amusing and entertaining than American romance movies. American romance movies are more or less predictable to me and that makes them boring (to me) and some are simply too obvious. But anime which has romance and slice of life hook me up to the screen because they behave in a way that is hard for me to predict which brings entertainment (to me).
Once in a movie there were no hints that two characters had feelings for each other. No hints at all. I thought they were just friends. And then in the end they kissed. Me reaction was:

. Totally unexpected
