Revenant is an occult mystery thriller and not a horror, so don't be too scared to watch this masterpiece. There's a lot of suspense to keep you on the edge of your seat, but nothing gory. It has a unique and interesting plot, which will keep you thinking and guessing, and thought-provoking themes. Above all, it features jaw-dropping acting from chameleon Kim Taeri, who has given us two more iconic characters in Sanyeong and possessed Sanyeong to join Na Heedo, Go Aeshin, Captain Jang and Sookhee. It's amazing that she transforms with each role without a trace of past characters. Revenant is thoroughly recommended and joins Mr Sunshine and Twenty-Five Twenty-One as my all-time favourite dramas.
