Finished it, and honestly it was great. Watched it with my parents, and surprisingly they liked it as well (my mom was really into it especially, though the 40's-50's soundtrack and Walton Goggins did most of the heavy lifting getting her hooked).
(I'll go ahead and put spoilers up for the finale ep in case people are still wanting to discuss prior to that).
The finale actually felt like a good payoff, even if it was mostly cliffhanger-bait. If we're comparing it in a broad sense to Fallout 3's missing father-centric motivation, then the show's mystery as to why he disappeared was at least interesting, and the show had the stones to make the selfish asshole father character an actual villain, instead of having everyone in the game trying to convince you that he's wasteland Jesus. The nuking of Shady Sands ended up actually being integral to the plot and not just an afterthought, so props to the writers for that (and it was fitting imo that the act was essentially perpetrated by Vault-Tec). Speaking of, I know Bethesda-brand Fallout dwells a little too much on the Pre-War stuff, but it was kinda cool to see the birth of Vault-Tec as we the gamers know it (horrible Nazi-esque social / science experiments), and it was a neat twist that Cooper's wife was the brains behind (or at least the spokeswoman for) that very thing.
Overall it was one of those shows where I got to ep 6 or 7 and thought 'uhh, I'm a little worried that they won't be able to tie this all together,' and thankfully they did do a good job of bringing the season to a close.
Looking ahead, the one thing that'll make or break S2 is if they can get Wayne Newton to come back and voice Mr. New Vegas.
And I'll bet ten bucks that the Brotherhood uses the cold fusion tech to power another Liberty Prime, or a 'Prime' robot with a different designation (my fanfic headcanon has always been that there's a 'Patriot Prime' and 'Freedom Prime' out there somewhere.)
