I'd hate to say this, but Digimon IS a kid's anime. Even in Japan it's for kids. The difference is in our cultures. What Japan considers to be for kids isn't always what America considers to be for kids. That's why a lot of anime series get so heavily edited when they're brought over to the U.S. because the American companies are trying to keep the same target audience that series had in Japan (like with Sailor Moon). But just because a series has a lot of touching moments in it doesn't mean it's not a kid's anime.
If Digimon weren't a kid's anime, there would be tons of violence with bodyparts flying all over the place, tons of nudity and sexual content and stuff like that, but Digimon is an innocent series that can be watched by all ages because it's for kids. That's why Digimon has been aired no such networks like Fox KIDS, ABC FAMILY, and Toon Disney. Disney movies have a lot of touching moments in them too and those are kid's movies. However, just because a series is made for kids doesn't mean that it can't be watched by adults. Nobody ever said that adults can't watch children's anime, but Digimon IS a children's anime. I like Digimon and I'm an adult but I'm not afraid to admit that it's for kids. If people have a problem with me watching kid's shows, then they can just stuff it.
