He's responsible for his performance within the bounds given to him by the writers and director. I haven't seen any of the Superman movies, but his performance was by far the best part of the Witcher series.

Well, just so you know, within the bounds given to him by the writers and director, he's a terrible Superman, unless people wanna argue Snyder specifically told him to act like a generic tough guy that doesn't speak much. He also played the same character in The Witcher, which is really not who Geralt is. Admittedly, I dropped the series halfway through the first season.
