People complaining seem to have never watched anime. And the revered Ghibli films (love Mononoke!) look pretty much just like that, with slightly differing art style. That's anime for you, choppiness and all.
Going in with the right expectations, i like what i see, especially the Japanese trailer. I said from the beginning, don't expect big box office returns, the brand will help a little but this style of animation has had a niche existence in the so called west.
