Definitely a five star production but I gave it four stars because there are many parts in the series where the excitement is not exciting at all. The Fold is a great asset to the story, but it's never scary in the series and the batmonsters look predictable. I also believe some scenes are really static when it's supposed to tip you off your chair. The production itself is amazing but some design choices are just too far away from reality. A ship/sled that runs on Grisha wind is a very weird choice to pass the Fold when there's wheels, metal, machine guns and - apparently - knowledge of how to build a train or tank. The Army knows what's out there and they go in completely unprotected. I also believe the Russian parallel universe is too close to real 18th history where the fantasy part never happened and never will.
