The show is not as simple as you've seen it from the trailer. It has a little bit more complicated stories and characters, but not too far off. It has brotherhood, bloody fight, mukbang, and above all, it's a fast pace show. The choreography of the fights in this show is also well done. It's just as good as another korean show from Netflix, My name. The martial arts or fight actions scenes in modern korean movies and tv shows are arguably better than any other action movies whether it's from hollywood, or outside of hollywood. They has more realistic fights. It's fast and furious literally. They don't have those showy exaggerated moves that look like choreographed dance. Unfortunately, this show also has those typical cliche moments like My Name especially those tear-jerky ones. That's my biggest pet peeve in korean tv shows and movies. Although there's a sudden change of pace (It was quite a ride until episode 6), and the ending is a bit rushed and shortened, overall, the show is quiet entertaining. The fight scenes are worth visit more than once. I give solid 7.5/10.
