Hey look, Rings of Power is better than House of Dragon.
OH EM GEEEEEEEEEEEEE
hahaha I get that you're trolling, but it seems most of the reviews highlighted the strength of ROP, which is visual & sound, which is not surprising as compared to HotD.
In terms of world-building, I expect the similarity which is slow world-building.
In the end, we have to compare the finished product with some adjustments vs the appendix + limited content from first age with invented characters quite frankly, not many would ask and have to invent stories. I mean, if you ask me whether I want to see One-Eyed Aemond or Arondir the lost Silvan Elf, I would choose the former. The weak marketing from ROP doesn't help either.
Not to mention GRRM still advised on the HotD, so that's a plus for the long term.
