I was actually hyped to watch this action movie starring Wi Ha Joon. After reading the synopsis, I was expecting great action scenes and a great character development.

Even though the actions scenes were good, some parts of the movie was still lacking. I was watching this movie together with my friends and one of my friend said "the action part was great, but I felt like there was no end goal in the movie. He got in prison, learned how to fight and beat up a guy, thats it". So yeah, my friend also felt like there was some lacking parts.

If I'm going to be specific about what was lacking, I can start with the beginning of the movie. We see two parts, one part for each main character. The first one is about Do Hyun and it shows what led to him getting in prison, what I wanted to see more of here was the longing and sadness he felt for his family members, you don't really see him thinking about them throughout the movie. About the part with Woo Sol, it just shows them having a fight and Seok Chan provoking him into stabbing him with a pen. All of that felt unrealistic.

Halfway through the movie, we see Seok Chan joining a gang because of his harsh and brutal fightingstyle. However, it didn't really make sense for him to join this gang, it didn't add anything to the story, it's not like we see the gang members attack Woo Sol.

At the end of the movie, we see Woo Sol free and he is visiting Do Hyun in prison. Again leaving us with a sense of wanting more to the story. E.g Do Hyun could have been set free from prison and we could see them back in their normal lives, but yeah, we didn't get to see any of that.

In comparison to the lacking parts, it was great to see the inmates going from stonecold enemies to friends with a little bromance. All it had to take, was them accepting each other.

I think I would recommend this movie to someone who doesn't really care about the plot and just wants to see some action scenes.
