I mean.. people tend to love whatever original IP for a reason, pretty understandable they get a bit grumpy when there's some kind of re-imagining going away from the core story/themes/whatever by those adapting it (see the current Witcher mess).
There's a little bit of wriggle room to change and expand some stuff (as TLoU has done really well imo) but its a really fine balance, by and large I think yeah, you kinda do have to stay pretty true original work. Thats if not pissing off the original fan base is even a goal - some stuff clearly gets re-worked for the express purpose of catering to a new fan base.
I think if there's themes of Fedra's corruption/fascism in the game that get expanded and explored it's not really deviating from the themes of the game, but each to their own.
