It's too serious and preachy to be enjoyable. There is no one to root for. No favs. No OST to make me cry. No love story to make me smile. No jokes. Moral of the story: humans are greedy, people are willing to do a lot of bad things to get what they want when they are pushed into a corner. There is a lot of luck involved in our life outcomes. Gi hun going back? Doesn't even make sense. He barely scraped through the games. lol
The ending is like when you get a meal you have been anticipating then the meal is just average. It's Meh...
