What this mini anthology of films based on the theme of Immortality all have in common is they have nothing to do with the theme of Immortality.
It might as well be called 'Wolverines siblings'. Poorly writen, hastily thrown together this 'Not dying and healing fast' series of tales misses the mark by a Continent.
Immortality is the concept of living forever and experiencing eternal life, it is measuring eons as the rest of us measure decades. It is loss and madness and eventually craving death. What it is NOT is suddenly realising you can't die. This could have been so much better; consider the anguish Connor MacLeod goes through in Highlander when he sees everyone he loves pass away over the ages. Think of the heartache of Gary Oldmans Dracula when his wife dies. Even 2020's 'The Old Guard' took the time to look deep into the curse of Immortality. This pitiful collection that all end abruptly however, refuses to go near such deeply philosophical matters. Instead it's as vapid and as inconsequential as Hayden Panettiere's character in 'Heroes': "Oh no! I"m hurt! Oh wait, I'm fine!"
By all means give it a watch but I guarantee 30 minutes after it ends you'll be hard pressed to remember any of it.
