When you say researching, do you mean the video game lore/details or just spoilers for the show?WestWorld was consistently plotted all the way through, especially since they stopped in the middle of production to map out the entire story until its end. The 'twisty mystery' of it all was the point.
The Nolans don't have any creative input on Fallout, though; they're merely Executive Producing, with an occasional stint in the Director's Chair.
Also, the things that I read that killed my enthusiasm start a couple of episodes beyond where I currently am in Season 1 (I just finished Episode 4).
