I think it has the writing of a soap opera, plotlines does not make sense, characters have an average IQ near zero, full of internal inconsistencies, without any sense of scale, space and time. "Dinner time TV" that is more enjoyed watching it in the background, but with a wasted huge budget - some good showrunners could have made it a least on a Game of Thrones level series. The "Inside of episode" stuff is really comical when the showrunners and directors speak. Sadly it's the only "Middle-earth" series as of now.
Ah, I forgot: every few minutes there are callbacks to the movies + quotes straight up ripped from them but placed at random, like a sit-com.
