If you like action, bromance, political turmoil, and saeguk (historical) dramas, then this drama is for you! This is one of my favorite dramas! The fighting scenes are some of the best I've seen (and no, it's not wire acrobatics, thank goodness!). This is a drama to watch for action and the loyalty between three friends, it is not a drama to watch for romance. However, the past romance (between characters I won't name) is very well done. On the other hand, the romance between the other characters seems forced and more like an afterthought on the screenwriter's part. Don't judge this drama based on the first episode, because the first episode is a little confusing. If you are just watching this drama because of the actors, it takes a few episodes for the young Dong Su and Yeo to grow up, so be patient, I promise it's worth the wait and it's important for the storyline! I did not give this drama a ten because: 1) the forced/poorly developed romance between certain characters, 2) the plot slows down midway (it picks back up again, but was not as good as the in the beginning) and 3) the ending (it seemed like a forced episode that was unnecessary and out of place). So all that aside, this is definitely worth watching, especially if you love action!
