The biggest problem with this series lies in its timeline. The last couple of episodes have some serious inconsistencies; for example, after the destruction of Syntra, the character spends over four days traveling across the land, while the Witcher seems to have been there only around two days prior to that event—I won’t go into specifics. I also found the dialogue problematic; the modern slang feels out of place in a medieval fantasy setting.
