Good: Nice special effects, nice wardrobes, nice sets, the ludicrous violence fits right in with the universe, and particularly the performances from the actors are very good. At least visually, it looks way better and the effects look way more convincing than 3 Body Problem, to use another recent show as a comparison.
Bad: apparently the show disregards New Vegas lore (personally idk I never played it), I think the editing is super bad, the story is average.
