This TV show along with "Humans" have been the best ones ever. But all great things aside, I have two critical points about Squid Game: 1) If the old man (who was behind all those things) was supposed to survive the deadly games while participating in them just for the fun of it, why did he risk his life in the Tug of War? It was foolish and risky to be there because having two girls and and an old man in a team can definitely make it lose to the other team which had apparently young powerful men! As the mastermind of the games, the old man wouldn't normally want to die there, so what was that stupid decision to go into Tug of War!? This scenario wasn't logical in the screenwriting.
2) What the hell happened to report of the police officer who escaped the island!? The police didn't pay attention to the report and the missing of the officer and back up forces were never sent to the place. Logically, the police department could easily track the signals sent from the officer's phone when he contacted his boss (even after one year nothing was done about that!) This was another defect in the screenwriting.
But all in all, I really enjoyed this series and am looking forward to the second season. By my critical points, I just meant that the scenarios in a movie or series should go logically. Thanks anyway for making such a great TV show
