This is fantasy. Until GRRM came along, it was a genre that was basically defined by a young adult becoming a hero and saving the world, in a battle of good vs evil.
One has not read the Rift War by Raymond Feist it seems. Magician was hardly about good versus evil.
Characters with moral ambiguity or proper depth to them were nearly non-existent.
Tolkien basically created the genre. GRRM made it an adult genre.
Beg to differ, but Feist, Melanie Rawn, and a number of others were up to bat long before GRRM hit the scene.
It's hardly cliche even across multiple genres, and certainly not in a fantasy setting, dark, high or otherwise.
Cliche? No not really. Complex is actually the right word in this case.
Sorry to disagree but the drunk abusive husband has been done to death, and that's what he boils down to. Ymmv, of course, but I found him trite.
Which is why a vast majority of the fans found his character and his story absolutely amazing.
(easy enough to check on reddit or witcher forums etc.)
And the vast majority of the fans seem to like the insane amount of female skin that gets flashed, so pardon me if I don't have faith in the majority opinion.
Now, you can not like him. Or his story. He's an abusive husband after all, very little in this world is more despicable or cowardly then beating on women - especially if you're a soldier-type, bear of a man.
You can not like him... But not because "he's cliche".
Yes, I can. And have, and will continue to do so, because that's my opinion of his character. You differ, but that doesn't make your opinion holy writ. Nor does being the majority opinion.
I found the writing in general to be okay, but the baron was a fat drunken abusive oaf. I swear there's a trope for that somewhere. He would have been a lot more interesting if they'd been more subtle about it.
As for redeeming qualities... So he was nice. Bad people can be nice, but it doesn't redeem them. He's an abusive murderer and the whole being a lord doesn't cut any ice with me. It doesn't make the fact he's got ***hole blinking in big neon letters from the moment you meet him a nuanced character.
