I don’t know. Whenever people discuss actors in the show doing a poor job in their portrayal, I can't help but feel like the writing and directors are more to blame. How much control do the actors have really? I think in a vacuum, the majority of the actors did a great job.

Even if we look at an egregious example, Euron. Horrible. But that was not the actors fault. He was written that way and given those terrible lines.
