War of the Rohirrim had its share of problems, mostly centered around the animation and the script could use tweaking. But it at least tried to stay true the world and the characters.

Rings of Power didn’t even do that. With a five year plan and a good script that tried to adapt storylines and two experienced showrunners. It might have worked. It didn't even try. Yes, it didn't not have rights to the Silmarillion. That being the case it should never have been done without full access to tell the story. But that didn't matter either. It was made only to make money not to tell a faithful TV adaptation. It COULD have been great. But no. It is schlock because Amazon didn't care to make it good. Only to make money.

War of the Rohirrim has problems, true. But the biggest problem was the animation. Rings of Power's biggest problem is the story and the treatment of the characters. It rips the fabric of Tolkien's world to shreds. Among the tatters it chose character and place names and told its own story, a pretty crappy "modern" fantasy story that was not designed for Tolkien fans but the general population who now think that this schlock is Tolkien's world.
