Season 1 was ok.

Season 2 was weak.

Season 3 was awful.

Season 4+ don't deserve my time.

How could the writing be so bad?

They had access to the source material and on top of that, a vast fanbase coming from both the books and the games, but no! No, no, no they had to ruin this universe and turn this series into a nonsensical time-waster.

Season 3 is a confusing mess. The Siri-Geralt-Yen situation is a glorified babysitting, or a family proxy (how is that interesting in a lore-rich, high fantasy, action setting?). This is simple and boring. Except from that, there is chaos. I cannot even understand or remember who is who and what is his motives and alliances. There is so much time wasted in politics, and so much screentime for people the viewer simply does not care at all.

PS No wonder why Henry Cavill wants to leave. Without him this series would be torture.
