The 0 or 1 out of 10 ratings are from people who actually really hate the idea that this big company thought they could use their money to buy one of the most well known works of modern fiction and butcher it. That is an honest review. This story has been known around the world for over 60 years as one of the best works of English fiction written in the modern era that influenced a whole genre of writers and creators in books, television, movies and games. No I don't think those are all dishonest reviews.
On the other hand, there are people who legitimately believe that Tolkien is no more special than any other IP and is just a story with no particular importance or meaning. To them it is just a TV show and deserves to exist and they may believe it is unfair to judge it beyond that. So for them the fact that Amazon spent all that money and produced something in the first place for this IP is all that is required to get a 10 rating. Therefore some of those are also honest ratings. Everybody isn't a lore nerd.
