I don't watch anime usually except for Shin-chan when I was a child, that rocked!! Probably wasn't aired in America for being too dirty or something (even though in Spain little kids watch it naturally, lol). I still find it funny when I get a chance to watch a little.
As a kid everyone watched Dragon Ball, Captain Tsubasa and Pokémon but I never got into those. I didn't care for the overdramatic superlong sequences. I did watch Dashu Kappei. It doesn't have a Wikipedia page in English so, again, I guess it was too dirty for American audiences. It was called Chicho Terremoto in Spanish.
Dunno why I just liked watching little Japanese kids dreaming of 20-odd girls and looking at their panties, lol.
Other than that, my girlfriend loves Naruto so I watch it with her these days. It's entertaining and cool often, but sometimes it drags for too long. You get full episodes of people staring at each other, thinking, and having flashbacks. And I realise this is quite normal in anime but sometimes it's overkill. I still like it though, but I don't know if I would watch it alone.
I guess I have never watched anime for adults though, so I can't comment on that.
