Pros:
-interesting premise and concept
-nice film texture, sets
-fine actings from the cast
-quite gripping and thrilling during the games

Cons:
-some draggy parts although this only 9 eps lol. Maybe got too much talking
-old man plot twist need more explanations?
-i wish there are more game parts and more challenging games lol
-cliches here and there

But overall a good production and enjoyable watch. Love that ifs only 9 eps. With the ckiffhanger at the end, will they make a sequel?
