The animation was smooth and synced with the movie nicely.
The visuals and concept behind them, especially the transitions where fun and engaging.
I almost gave it a 4.5 for seeming a little random, but honestly it had a more clear narrative direction than some movies, so I let that go.
Oh also the character design was great, and really portrayed the "beings" personalities in some fun way.
The small snail like pizza guy definitely gives off a servile air because of stature, dress, and facial expression. They don't even look that confused, just more like "ok, that's life I guess."
