I like all forms of animation because it gives the content creator(s) more freedom to share their vision than a lot of other forms of media. It is also cheap enough that more content creators can share their visions. Visual media such as animation is also more accessible to content consumers than other media, such as books/text. (I love books too, but text does require that people know how to read, and have an imagination that can animate the story internally.)
That said, I typically dislike content from companies like Pixar and, especially, Disney. Their stories are like something put together by committee, filtered through political-correctness focus groups, greenlighted by the accounting department, etc., etc. Certain topics, characters, and situations are forbidden, even if they add value to the story. Their content is always, always more concerned with the bottom line and corporate image than telling/sharing a good story. I often get the feeling that the only reason that there is any entertainment value at all is because if there wasn't any then there wouldn't be any profit to be made either. The best that can be said for a lot of it is that it is technically well done.
Not to say that I think all anime is great of course. In fact, I'll put it on the record here and say that most of it is not. A lot of it is crap and not even worth the time to watch it. A lot of it is low-budget, and it shows. But when it is good it is really good. The best anime is not something that would have ever even been allowed at someplace like Disney or Pixar. With anime I don't feel that there's a lot filtering/distortion (aka censorship) going between me and the author(s) like I do with a Disney production.
