It's hard to do it when everybody on the bus looks like they are either about to pass out or any attempts at eye-contact would involve getting yelled at. Forget talking, we should all be able to just smile and nod at each other.
... oh yeah, this is supposed to be a "movie review". Good movie. Simple animation and graphic style, which appropriately deviates from what is observed to what is being heard, which is the keystone of the project. It poses a strong, relatable idea, has plenty of reason behind why the idea should be considered, and it ends off on a humorous note just for good measure.
We need more movies like this. Keep up the good work!
