Escorting only virus survivor and hope for humanity is so original also?
A story is made up of its characters and memorable moments. We dont know how Deacon will evolve. And some of the situations he gets put in sound interesting and it sounds like you're gonna meet a bunch of people that live in small to large compounds.
Theres also the fucked up ravagers/cult like group of people which is "generic" for sci fi storys but it still works well and is beloved for series like Firefly.
Sounds like you're judging a book by its cover.
