The open question is, will it bomb? In theory, a FALLOUT show should be the easiest damned thing in the world to produce. You spend most of your budget on flashy-looking crap, and use old sets that have been weathering in the California semi-arid wastes for decades for the rest. The plots are all Mad Social Science and unsubtle parodies of social commentary; stir in a little mild body horror and dark humor, and just go from there. This is not hard.
And yet, all sensible people are worried about this show.
