It's all a bit boring (and pointless) complaining about the race. They are what they are now. As I keeps saying the show isn't going to be made or broken on the casting of brown small people.
IF, and it's a big if where i am not accusing anyone, The shows quality is decided solely down to the colour of someone playing a certain character, that is a you problem and not a problem with the show. If you can't leave that prejudice at the door and just accept an actor playing a role of a made up race without getting all in your feelings, again, it's a you problem.
Criticising the acting or the story is completely fine and should be welcomed but picking the 'race' of a made up race as your hill to die on? Odd choice.
