In response to the original post that started this thread...my guess as to why anime is so like-able is because, the Japanese are VERY soulful people. Unlike American cartoons, they're not afraid to get down to the nitty-gritty and show 'bad' things happening. I mean, GOD FORBID any American cartoon series would show good guys getting dead!
I first realized this with my first ever exposure to an anime film on the Disney channel when I was about 11 years old. It was Osamu Tezuka's "Unico". I couldn't explain it then, but somehow, I *knew* what I was seeing was unique, because this had themes that would be considered too dark for other 'friendlier' looking cartoons on regular TV. I guess I've had that since I was even 7 years old, in that I've always been fascinated by the darker side of human nature...
But anyway, I like to think that most other people like anime for the same reason I do: an escape to something more darker, cuter, or intense then anything that America tries to feed us. Hell, even NON-anime fans love the movie 'Akira' for both it's extreme, over-the-edge animation style, storytelling and voice acting.
Just my 2 cents...heh
