It sure as hell ain't objectively good, pal.
My point is hardly any art is objectively good or bad as it boils down to each individual's taste. I've just thrown a minor tantrum today browsing through Guardian's album reviews where rock albums hardly ever get 3 stars and Kanye West is a sort of musical Messiah, meanwhile metal doesn't even exist.
Also Toss a Coin to your Witcher was never in the games - it was made specifically for the series - a multimillion Netflix production, same goes for The rains of Castamere, so I would expect higher quality from those than a medium sized gaming studio.
