It's probably the strongest part about the movie — it deals with perspective of immortality from a mortal's perspective in a very realistic way, which is normally thrown by the wayside for more simplier tropes in entertainment. Not that it's wrong to like that, it's just hard to find something that doesn't these days. It comes across more like a well written hard sci-fi story, yet it's mostly just a group of people talking. It left me thinking about immortality from a normal human's perspective for a long time. He explains how it changed him, and where he started from. It's very compelling in my opinion.
