A good idea left unexplored, lazy world building when it should have been the main focus, average plot that we already have seen - the usual French TV series.
Of course they obviously had no money and few ressources and it shows, but they could have exploited it. The fact that the story happens, apparently, close to 100 years in the future but the technology is the same (because no money) could have been a way to build the world if explained. Immortality made technology irrelevant so they stopped innovating. For example.
The main issue remains that they did not really think about their own ideas a lot. It's very superficial. Immortality is boring and the youth feel out of place, ok, but go deeper than that, show us how it would radically transform human life and society and the world. Sadly, it went nowhere.
