So you see no reason why the Author of the work the show is based on is relevant? Isn't it strange how here you are arguing the source material and Tolkien can't be referenced in a discussion about the show while at the same time others have complained that the show doesn't have enough of Tolkien and the source material? Lmao.
That is on top of your unrealistic expectation that a show has to define Dwarves, Elves, and offer a introductory class on its world prior to showing even the first episode. What show has every done that? Made its viewers an expert on its world prior to watching any or all of its episodes? This is again where your bias shows through because you are setting impossible expectations for the show then complaining when they are not met.
