I watched this on the spur of the moment after having 0 intention of watching it previously, because tbh how many times have manga/anime fans seen this survival game concept? Growing up with Japanese entertainment, NOTHING about this show was new at all, but I still loved it. I suppose for Westerners it might be new, but for me the shock factors or disturbing qualities didn't stand out from originality but from the pure execution. I could say the majority of the plot turns were predictable as well but the pacing and performances were SO good, that it kept me on the edge of my seat. The violence/gore wasn't emotionally or mentally straining and was easy to get to used to after the initial shocks of the first two episodes.
I LOVED the detective. Passionately :D and not just because that man is incredibly fine, but his character addition really added to the quick pacing of the show, mixing in another storyline so as to almost give us a breather from the dirty inhumane warehouse feeling the other characters endured. I believe that the alternations of character/story focuses was what was really done well because it always kept you rolling and focused. A "next, next, next action" experience.
The only reason I'm not giving it a 10 is because I really felt that the ending of some characters was rushed. Episode 8-9 definitely lacked the full emotional appeal of loss for me and I was mildly disappointed but I understand there was a time crunch.
I've never stayed up all night to watch a show before, but I did for Squid Game. I was absolutely groggy the next day but it was worth it. I'm currently rewatching it with my mom, and it is still an incredibly crisp viewing. The camerawork and colors were executed very, very well and I look forward to watching Hwang Dong Hyuk's other works.
The "novelty" of Squid Game that's all over media is 100% Western hype in my opinion, but tbh with how well done this show was, it probably deserves it.
