You just dont need to invent a wheel if you got no talent. Word to word adaptation would be much better. Also, bad writing is not the only problem of the show, sadly. Geralt, Jaskier and Roach looked above average, though ALL of the cast members should blame the writers and producers for not letting them to be likeble. As a fan i am very dissapointed, i was waiting for this show for too long and now i feel robbed.
