The show is yet another mediocre adaptation distributed by Netflix with poor character developments and a messy plotline. Characters felt flat with their dull backstories; even characters who died have no real impact on us viewers. Although the costumes and atmosphere look pretty amazing to look at, you can easily be distracted by how some of the CGI effects are noticeably bad; Yes, I'm looking at you, Alina (For some reason, it reminds me of how Netflix handled Iron Fist's glow). However, the soundtrack was great to listen!
All I can say is if you have read the Grishaverse novels, then you might be for a treat as you already have come to love the characters and have the knowledge of how a Grisha works. If you are just a casual viewer, then you'd be left out with no explanations whatsoever. It's like the show assumes you've read the books on what they can do.
