The show is really good at the start. I think I liked episode 3 the most, got me even hyped for the rest. But it all gets worse the further it goes.
otherwise
- absolutely horrible costumes, all of them. there is not a single one i like really, maybe only Zerrikans looked sort of all right or some guards. the same goes for most of the weapons, some are utter shit, crossbows for example are just i don't even know meh... crossbows and condoms in homo armor... who the hell was so drunk to draw them and so stoned he let them even go through, or dryad's costumes made from plastic
- the show is rushed, i don't believe anybody not reading the books can make any sense of it.
- monster design is not so good either I think. I can't really say I liked a single monster in the show... well geenie was great, but that doesn't really count. Striga was really off I think - a pulp of undefinable shape with teeth. Maybe hedgehog was ok except for his armor, it was supposed to be all spiky. Yarpen's face is awesome and his speach and scottish accent too, but his companions and their skinny bodies are... well they just look like a joke. Even Tyrion looked tougher.
- not that great casting, witcher I was thinking is going to be the worst is actually ok. Yennefer looks more like a cheap whore than a refined cunning woman. Marigold is crap. Ciri or Tissaia are awesome though.
- script is alright in the start, there are some things not mentioned from the books (or i don't remember them) that are actually really cool. I really liked piglet part for example. Didn't quite grasped what made her so special in the end though. The later the show goes the worse it gets imho especially when the script is not following the books.
- combat scenes are pretty good, some are even excellent like Blaviken fight is just super great for example.
- battles are anything between below average to alright.
- dialogues are alright, some are even pretty good, but again as the show progresses it gets worse.
If I'd score it for the start I'd give it 8/10 easily, the end deserves like 5/10
