I’ve watched the first season (8 episodes) and I think it’s pretty good. I personally think the first episode was a little slow getting into things. If you don’t know anything about Fallout it may be a bit confusing at first because they don’t really explain much of the Fallout lore or how things work in that world, but it mostly all comes together by the end of the season.
Apparently they’ve already greenlit a second season so that’s awesome, I’m just sad we’ll have to wait until probably next year to see it.
