Set at the start of the 17th century, three years after the end of the Imjin War, Kingdom takes place in a fictional, medieval-inspired Joseon (modern-day Korea) and blends political thriller and elements from zombie horror.
Finished Seasons 1 & 2 - A absolutely refreshing show of dramatic force. A refreshing upbeat zombie tale done with seriousness, drama, and tangible consequences. I cannot recommend this series enough.
