Hype Backlash: This short was marketed as taking hand-drawn traditional animation and "pushing it through a new process that would meld it seamlessly with CG." While it does achieve that goal splendidly, a development reel on YouTube reveals that the animators still had to start with CG in order to achieve this look, prompting both hardcore animation purists and veteran animation pros to claim the staff as "lying", and claiming unnecessary training. "Why go through this whole process if the end result is just going to look like hand-drawings?" They are in the minority, though.
Expect a lot of people to worship the short as a masterpiece of writing, design and character. Expect just as many people to disagree and get their heads bitten off by the fans.
