Sadly, IMO Squid Game 2 is not as spectacular and interesting as the original season. It is still fun enough to watch as the protagonist is on a path to exact revenge on the evil oligarchy but since the originality factor has worn off, this S2 seems a bit more rushed (2-3 less episodes) and less entertaining and less thought provoking. YMMV.
ETA: When I wrote my initial impressions about S2 in the above paragraph yesterday, I had not watched the 7th and the last episode of the 2nd season. I was wondering why the 2nd season was even shorter than the original series and why they were rushing through the "games" because after all, in the original series, there were some interesting and elaborately schemed (to me) survival games. Without exposing those who have not watched yet to spoilers, it appears that this S2 is going to be like one of those splitty seasons like GOT had it's season 8, part 1 and part 2. I find this type of cliffhangers also very annoying!
