The story is clever and well written. The cinematography is beautiful. The cast is great in their respective roles. CGI is pretty decent. It draws its premise from the annals of the Joseon Dynasty. The movie takes inspiration from the legendary creature called "haetae" from Chinese and Korean mythology. If you look a bit deeper into the plot you will find that the movie is also a commentary on politics, powerplay and manipulation. The story keeps you engaged and guessing. I found myself genuinely rooting for the leads and the people on their side. Would be a loss to miss, especially if you like this genre. The chemistry between the cast is enjoyable and doesn't feel forced. The father-daughter relationship between Yun Kyum and Myung is portrayed beautifully. Overall the movie is a highly entertaining watch.
