My main criticism is that they have done literally nothing to establish or explain the rules/quirks of the world. If I wasn’t already a fan of the games, this show would be confusing as fuck. They expect you to just know about the NCR, the Brotherhood, what a ghoul is, what caps are, etc. Like, I hate exposition, but this is going too far in the opposite direction with it.
The other is the place and time. I watched all 8 episodes and it seemed like it took place in multiple parts of the country between at least Massachusetts and California considering they say they are in the Commonwealth at the beginning, but clearly are in Los Angeles pretty much the rest of the time, and it’s unclear how long McClane and Maximus’ journey had been due to the weird time compression. It’s almost like a TV show done like a linear game where you just move from set piece to set piece, while losing all the stuff you do in between.
Other than that I loved it. If it didn’t have actors I recognize and have the studio logos in the opening credits, I could easily believe this was made by hardcore fans of the games as a independent project.
