oh wow, all so emotional to end with something funny :P

Inoperable? Was that supposed to mean it was cancer? You know, "cancer" like "cancel". Whatever, it was a nice cartoon. The animation was great. The punchline could have been clearer.

It was quite creative. You show a nice interesting world. The simple title is great as well. I do understand this father-son relationship. Weird for cells to do it, though.
