Animation is a medium, and as such, the only valid complaint about it is stylization. There are some animators that I don't particularly like, and there are some that I love (Hayao Miyazaki is amazing). But as a genre...it's not one, so one cannot dismiss the whole just because suck like Naruto exists and is popular. I could point out popular love action things that suck as well, but that does not mean that the entire medium sucks. Personally, I only like what is good. Some anime that I do watch and like: Monster, the first half of Death Note (the second half sucks, and it's not just the opening music), Ghost in the Shell (especially Stand Alone Complex), Azumanga Daioh, Cowboy Bebop, the remake of Negima, Studio Ghibli movies, Samurai Seven (Akira Kurosawa directed it, and it's basically a show based on his epic Seven Samurai), Paranoia Agent, Wolf's Rain, and Trigun.
As a side note, anime is a stylization of the medium of animation. It came about because it is simple and yet still holds much of the communication value (at least, many animators can) as even live action. The way to go about making a great animated film is different than live action, as you can do some new things with it and yet not do some things with it. That line is being blurred recently, what with the leaps in computer augmentation and practical effects happening, and with the animation becoming more sophisticated, but the way one goes about creating an animated film is different, and requires a different paradigm to view.
