I mean, it's not just a large cast, but morally grey. Like, the ironborn aren't really "evil" so much as they're acting in self-interest and want to be independent. Some of them like Balon are downright stupidly vicious ("let's stab the Starks in the back even though they're our natural allies, then expect the Lannisters to reward us with independence for doing what we should have done had we stayed loyal!") - others like Yara Greyjoy are just nationalists loyal to their homeland.
