That is a very odd comparison. Horror movies are stupid, they always have been stupid, and they have spawned a whoel plethora of tropes about how stupid people are. "Let's split up" being chief among them,
The Lord of the Rings is not stupid. The book, is excellence. The movies were excellence.
The bar is set at excellence, so that is what we expect. The Hobbit got a lot of flack, rightfully so, because it did not come anywhere near the bar set by the LotR trilogy.
The audience for Rings of Power is not even remotely close to being what it is for horror movies. The same people might enjoy both, but go into each with vastly different expectations.
This isn't just some people bitching and moaning about insignificant things though, there is so much inane writing in this show that it's downright baffling. It's not nitpicking to sit on the couch going WTF? when Halbrand suddenly intercepts Adar (from the front no less) even though he left the village after Adar and Galadriel. It's just dumb shit over and over that we're just supposed to accept no explanation for. Or 160+ (theonering.com counted) horses with riders that somehow fit on three small boats.
I don't understand what you need to do to completely ignore all this shit, but good for you. I can't turn my brain off to that degree.
