From the acting to the plot, everything about Boyhood was top tier. I loved the action sequences a lot, I wish there were more frightening scenes of Im Siwan without the mask.

All of the other actors were great too. One thing I liked about the show was the genre switch, it felt jarring, but quite realistic at the same time.

Unlike most of the other revenge/underdog kdrama, Boyhood wasn't unrealistic. Like, yes Jang Byungtae ended up winning against Gyungtae, but it wasn't because of his strength, but endurance that he had built for YEARS.
