The plot may be thin and felt so rushed up but the fights to me is just a fun ride. Great watch just for those action sequences. Kudos to the choreographer and the camera angles because they produced something so fluid and I can actually see how they "danced".
As for the story. When I heard that it would just be 5 episodes I didn't think it could do any good but I did try to keep hope up and well the plot line needs more work but I'm pleasantly surprised to find the whole thing watchable. They don't dig in deep but it's still easy to keep up. I do lament the lack of time to get to know more of some of the leads though.
The VFX bordering on uncanny is doable. I like the color gradient they chose. There wasn't any point where I went "TOO DARK" because I can actually see. They didn't hide the VFX under darkness and you know what. Kudos.
Warning: Bright flashing lights sequence in ep 1. Also had plenty of blood if you're queasy on that.
