I enjoyed the animated movie and felt the writing was better thought out than anything in season 2, which is full of contradictions and pointless character arcs i.e the mages, fringilla and cahir etc. The film was able to demonstrate the horrors of the trials to become a Witcher and offered an interesting take on witchers becoming redundant in the world.

I particularly enjoyed Geralts character reveal at the end (the baldness threw me). I think more spinoffs like this would benefit the show massively, as there is little in the way of explaining context in the show.
