On my side I played the first Fallout game a long time ago, but I am not very into post-apocalyptic settings (I was very much more a Planescape Torment fan at the time). I enjoyed Fallout on Prime Video very much - it was very neatly done, with a great exposition (a lot of scenes about the society before the apocalypse, which is not done in the games as far as I know ?), and characters having very different POVs and stories. The tongue-in-cheek flavor of Bethesda games is well reproduced (from Fallout, but also Elder Scrolls series from Morrowind onward - I played all of them).
I agree - RoP may have lavish pictures, but the story is way too classic - moreoever, first season of RoP and WoT may have suffered by using exactly the same trope : we don't know who is Sauron/the Dragon and we have to guess... which may work for those who did not read the books, but not for us.
Both RoP and WoT try to enhance the exotic world feeling, by displaying strange customs - which may work sometimes (dwarven singing in the Moria) or not (ritual mourning of a Warder), but both are missing an humorous subtext and take their characters way too seriously. On the other hand, both series try for an epic - which is not the case for Fallout : not all series should have the same tone.
