It’s kinda like a popcorn movie so far (ep 5). Enjoyable, obvious, fun. Campy. So violent it’s not.
I can’t recall any time Fallout was overly serious or, “hit home.” Maybe Cait’s companion quests in FO4? The “Do Androids Dream of Electric Sheep” mission in FO3? Even those examples are just well-told stories rather than emotional rollercoasters.
