I think, overall, if the show wasn't directly attached to Fallout itself I would've enjoyed the concept more. But because of all the stuff that carriers over, lore and all, it makes it hard to see this as anything other than a soulless cash-grab at best and a deliberate attempt to rewrite the franchise at worst.
Everything Fallout after New Vegas pretty much is just a cash grab.
But then again, if Bethesda and Tim Cain worked together to bring back pure Fallout, complete with the original themes of the game, you'd get a preachy mess whining about how capitalism, American nationalism, and reverence of the military led to the nukes falling on top of us. They portrayed the Cold War America that hated Commies as a cause of the apocalypse, while American capitalism barfed up tyrants like House who controlled New Vegas with an iron fist, and nefarious villains like Vault-Tec, which used surviving American citizens as guinea pigs for experiments.
Fallout 1 depicts a world devastated as the consequences of American exceptionalism and nationalism, and the Brotherhood of Steel which comes from the remnants of the US Army are characterized as selfish, apathetic bastards who send people to their deaths whenever people from the outside try to sign up with them. Fallout 2 depicts the return of the American state in the form of the Enclave; mass-murdering, power-armored Nazis who want to gas the entire world.
If the SJWs got a hold of that story and what it really represents, they'll never let you hear the end of it. The Fallout world's history pretty much shows that the American government are assholes, the American military are assholes, American capitalism barfs up tyrants like House and monsters like Vault-Tec, while the consequences of the USA playing God, the Super Mutants and the Vaults, brought people nothing but suffering 99 percent of the time.
The only game that was genuinely conservative was Fallout 3, what with the Brotherhood of Steel heretics in that game acting like a genuine American army protecting the commonfolk, while even the Enclave got toned down from omnicidal maniacs to dudes who just want to set up a warlord state using water. You can even donate money to the Church in Rivet City, and your ally in the final level is a patriotic American war machine who mouths off about how Commies are bad.
FNV, the message is that everyone sucks. House is a tyrant, Caesar is a megalomaniac, Lanius is a barbarian, the NCR is a worthless pile of shit, and the best way forward is to take Vegas for yourself and toss Oliver off the Dam.
