That's pretty good! I think I prefer how the Bones were animated too, though to be fair they are much simpler characters to draw, let alone animate frame by frame like that.
The animator mentioned in the video description that he thinks at least part of the movie should be in 2D (like the introduction or something) and actually I think that's a good idea. Don't know what Warner Bros. studio is like for 2D animators at the moment, but they may be able to pull something off along the lines of this.
I'm not crazy; I'm sanely-challenged.
