S1: 9/10
S2: 7.5/10
S3: 2/10
This review will primarily cover S3 - as this is the season that prompted me to write this. S1 and S2 are generally really enjoyable, S1 particular is written with some serious passion that makes its success so understandable. S2 feels a bit unnecessary but generally continues the positives of the original games, albeit a bit lacking in some areas.
S3 finds the series struggling big time. There are some areas it continues to do well - the acting is still decent particularly from the main character(s), the general premise stays solid (more on this later though), and the games continue to highlight the worst in humanity. Outside of this though, there are some serious problems with this season.
Firstly, the storyline - so much of it makes no sense or feels unnecessary. The plotline with player 246 feels completely out of place and is not beneficial to the general feel of Squid Game at all, it feels rushed and essentially serves as filler. The detective's storyline is incredibly lazily written too, with some pretty major oversights/plotholes. The writing of the VIP's is painfully poor, albeit understandable to an extent given the international audience - however S1 excelled due to their mysterious nature. They provide no benefit in S3 and instead serve as a serious annoyance throughout.
Another serious gripe I have with the third season is the absolute lack of authenticity that made the original season so enjoyable. Whilst CGI was certainly used in S1, it's FAR more noticeable in this season and takes away from the authentic, immersive feel of the first season. Things like the CGI dog, baby, and even some of the games feel either unnecessary or poorly done, really detracting from the viewing experience (particularly the dog, why was this CGI or even included at all?!). I understand that game ideas may be limited, but the feel of them in S1 was so much more engaging!
There are also far too many characters in S3. Having so many storylines mean you have 3x the characters to track, and far less time to connect with any of the main characters. In theory, the scene with the mother and son should have felt similar to the marble scene in S1, but I found myself feeling hardly anything for them due to the fact we'd not really developed a connection with them in the same way as we had the characters in S1. Instead most characters feel disposable and hollow.
Ultimately, S3 sees the soul ripped out of Squid Game. No longer a new, novel show that critiques so much that is wrong with the current world, it has almost become a tool of the very thing it critiques. The upcoming USA version is so hilariously out of touch that it may well serve as the final nail in the coffin for the show, which would be a real shame as I genuinely believe the director has a true passion for the show, but has been handcuffed by Netflix and co to produce a product he isn't truly happy with. Nonetheless, it's a sorry downturn for what promised to be an incredible show.
