As a fan of the book, Project Hail Mary was great. I loved that it stayed so close to the book, even for the ending.

But the story has aged quite badly. The world coming together to solve a problem for humanity seems so far fetched nowadays.

We would be waging wars about Astrophage, trying to exploit it financially as much as possible before the sun dies.
@bastianallgeier if you want SciFi based on that but with a silver lining, try The Bobbiverse
