So we've got one guy saying the aesthetic looks like the game and implying that's a bad thing (the games are the source material...?) and another saying a two minute trailer is leftist and refusing to elaborate. Cool.
The backstory of Fallout is that the combination of corrupt authoritarianism (in the US and China), unfettered capitalism (particularly the outsized influence of a handful of major corporations, such as defense contractors), and great power conflict (manifesting in arms races, nuclear proliferation, and wars over increasingly scarce resources) led to the end of the world. If that motif upsets you, and/or if that's too LeFtIsT, feel free to take your viewership elsewhere.
