I found this an interesting concept.
Originally watched this for the Henry Rawlings(black flag history) But found myself drawn into the idea of immortality and watching the little things around run him,living thier lives and really he not giving a stuff about them.
It was only the concept and interaction with an offspring that brought the main protagonist( Henry) into the world and socialise with anyone.
The twist at the end was good and happy ending sort of was a bit of a let down.
But overall less is more so two thumbs up and will watch it again and have me some interesting things to look up on my search engine.
