I can see it being hard to do orcs in a prestige TV series. "Always chaotic evil" race is problematic, to the point where even Tolkien thought so and was never really satisfied with the Orcs being always evil all the time.

I think Shadow of War did an excellent job of portraying Orcs. Some are witty, some are charming, some are scary, some are brave, some are weird. But every one of them is evil to the core. They managed to fill the orcs with so much life and complexity and personality without forgetting that at the end of the day orcs are evil. It was just so well done, i really admire it.
