The premise of the show is similar to Hunger Games- lots of people in an arena who are pitted against each other and only one can survive. The show starts off okay with an okay protagonist who has his share of problems many of which he is responsible for himself. Then it manages to grip you for the next two while establishing that the games were created to be fair and equal to these miserable participants. Unfortunately, it goes sideways from the fourth episode and seemingly stops being fair and introduces some other characters only to give our protagonists a chance to appear smarter. The games themselves aren't very novel and exceedingly turn away from children's games into the aforementioned hunger games. All is then conveniently wrapped up in the last two episodes without any explanation. It really irked me how many useless plot threads were introduced and remained unresolved. The show-writer believed perhaps that the audience would be dumb and hence enjoy the gorefest they have prepared without any sense. For each major plot thread to be wrapped up completely, each "grey" villain was turned into a complete psychopath as most villains at the end of k-dramas do. The games are built such that females do not get a fair and equal chance at them instead of that being the whole premise of each game. The actors themselves act well and deliver convincing performances. The music is forgettable.
