If you like narration as in Wes Anderson's film "The Budapest Hotel" and survival game dramas/movies that showcase human desperation like Squid Games, Alice in Borderland & The Platform - then you must watch this show. Worth the binge watch!

PRO:
• Almost everything - good plot, pacing, acting, suspense, moral lesson
• Unique Factor: narration like Wes Anderson film done by the main character (Floor #3), changes in aspect ration. Easter egg in the end where another character (Floor #7) opens floor to Season 2
• Compact format, but does due diligence to cover every character's backstory, changes during the game & after

CON:
• Not exactly a negative point - but the show does not give immense thrill, only cause we know of shows that have come previously like Squid Games and Alice in Borderland. So for some this may blur into the same category & not be unique.
• Personally did not like the sacrifice shown in the end, though it fits well in the story. But just my opinion that the finale episode could have ended differently.

OVERALL:
If this genre is to your liking - give it a watch, else skip. Not a unique-never-seen-before drama, but compact format makes it a good watch if you enjoy such thrilling survival shows that focus on how humans will do anything to survive!
