I'm not sure what paid critics are looking for in a show. After reading that Citadel received a 51% mixed review, I was pleasantly surprised by Citadel. It receives high marks from me for entertainment. I have watched the first two episodes and have enjoyed the acting, story, and cinematography a great deal.
I just finished Citadel and found it wonderfully worth my time. It was excellently storied, shot, and performed. Entertaining as hell. I am looking forward to the next chapter with unbridled glee.
