This show would be 50 times better with a script of GOT or Vikings calibre. The actors do their best with what they've been given but the dialogue feels like a 13 year old's fan fiction.
Visually it is great, costumes, scenery and special effects very good. Fight choreography not bad either. But every time a character blurts out a phrase reminiscent of a petulent 21st century teenager it makes me cringe.
But it does make the main Witcher series look even better by comparison.
