Forbes is a click bait farm thst bought the name of an old magazine. Pure trollage.
Now, it is true that big cross lije Amazon and Disney do seem to be weaponizing diversity as a hedge against criticism. However, since this is a 5 star show that is enormously respectful of the source material (speaking as a huge fan thst is deeply knowledgeable about Tolkien), in this case the trollage fully explains the review bombing, which is apparent when you consider the numbers from the verified critics.
To quote the Big Lebowski, "That's just like your opinion man." You keep stating, again and again, that this "is" a 5-star show, like it is some ontological fact, when what you're really saying is that you love it, and you can't understand why others don't love it.
Now I will give you this: Many of those that are giving it 1 star are probably doing so because of anger and disappointment. But again, I don't see a lot of obvious trolling - that is conjecture on your part.
As I said, I would probably give it 2, maybe 2.5 stars. I can see why an un-critical viewer might give it 3, but given the obvious problems with the script, acting, and plotting, I think 4 is a stretch and requires someone to ignore or not care about what makes good film-making, or deep knowledge of Tolkien and his work. 5? Well, I suppose everything is loved by someone.
So I'll go back to my original point to you: The phenomena of the wide divergence of opinions about this show is interesting in itself. Your answer to that is, "The show is amazing, and anyone who doesn't think so is wrong or, worse, a troll." My answer is more like, "There's no accounting for taste, but I'm still baffled by how knowledgeable fans of Tolkien and/or discerning film fans can give it more than 3 stars, but if some love it, more power to them - my view of Tolkien and quality film-making is very, very different."
As for the critics, I'd say that implies a combination of being "ideologically driven" and/or paid by Amazon to write good reviews (which there's been some examples of). The weird thing is that RT doesn't actually show any of the critics reviews, which is fishy in and of itself...
