If you like analyzing and observing , even if you don't, this is an amazing drama in the sense that it keeps you on your feet. The episodes are only 30-35 minutes but you'll probably feel 20 different emotions in the duration of one. What i didn't like was the ending? it was extremely stupid to me, yes i know that they're stuck in a loop and it restarts and yes i know who created the game and why they created it blah blah blah. i know all of that but the problem from the very beginning was that they were stuck in the mafia game? that has not been resolved whatsoever! is there going to be a season 2 for this or is this the end? There were a lot of plot twists and i genuinely liked this drama but kidnapping the WHOLE class?? yes time moves differently in the game but regardless where are their parents exactly? The beginning? immaculate, showstopping, had me waiting at the edge of my seat but the ending of the drama brings more questions than answers and that brings it down for me.
