I'm so excited!
Being a descendant of one of the founders of Silla (like many Parks and Kims in Korea), I'm happy to be able to watch this on Hulu! The subtitles seem a bit too simple at times, but I guess that makes it more readable than fully explaining all the nuances.
I've heard that the series departs from history quite a bit and that the writers have taken a great deal of artistic license, but also that it's really entertaining. Can't wait to watch the adventures of the first queen of the Korean peninsula!
