Sisyphus
The end was beautiful, every single person has a bit of a different story with Sisyphus, some say the stone he is pushing does not have a place to go, and it is just an endless path, others say that it does have an end, but when you are almost there you get pushed back all the way to the beginning, without taking in consideration the accuracy of any of this and Camus' work, I'll say that the end being a pile of all the stones he's pushed is probably my favourite interpretation of the myth. Simple, but emotional animation wise. Only thing is that even though the voice acting is on-point you might need to get some headphones because people could misinterpret the thing you are watching.
