Well, I read the first comic. It was a bit hard for me to get used to the differences in art style at first, but yeah, I enjoyed it.
(The ears were bigger. One of the characters looked different.)
My guess is the manga series goes on for quite awhile, so I probably won't be able to read the whole thing. (It's a lot easier to watch the show on TV than it is to buy the books.)
I haven't seen any of the series in the original Japanese, although I'd like to sometime.
