First of all, I don’t think it needs saving at all. It is what it is. Most people like it and I think that it barely qualifies for background noise. That is not a bad thing, nor do I think it’s a bad show. But everything that has happened in Fallout I have seen it better executed and in more interesting ways elsewhere. It’s cliche events, predictable story, characters have no agency and their arcs are flat, and it has a weird almost Disney like censorship over the whole plot. We almost never get to see the truly (few) eventful and important beats. But also even minor things that would be interesting or impactful to watch, they always cut or pan away the camera.
