People are upset not because the show is bad but because it's not as bad as they expected. In fact, it's quite good. This ruins their mockery narrative.
I do worry about that. The extremely negative sentiment IMHO is vastly out of any proportion to the quality of the show. Frankly, much of the criticism was based on misunderstandings of the characters and what Tolkien actually wrote anyway.
It’s not Shakespeare, but it’s nowhere near as dire as the anti-hype suggests. If it had come out without any connection to Tolkien, or the truly cringeworthy marketing, I think it would be doing fine.
