It's got the iconography and the aesthetics down pat. It's really worth it as a Fallout fan for that alone. For about an episode or two, anyway.
I'm finding the writing distractingly inconsistent, I outright dislike one of the main characters in a way that makes it hard to watch their scenes, and all of the thought provoking elements of Fallout lore is nudged out to explore Brotherhood and Enclave stuff again.
I would recommend it if you genuinely like Fallout. On it's own, I think it's a really, really messy show.
