Something I noticed (S1 & S2 SPOILERS)
I'm not really sure if this is indicative of anything, or if it's just a touch to make things more grim but I noticed blood is more present in Squid Game 2.
In Squid Game 1, often you aren't spending much time looking at pools of blood. Red Light Green Light, you run past the corpses, Dalgona, a lot of the deaths are off-camera and not focused upon, Tug of War, the dead players are all the way at the bottom. Special Game, everything is cleaned up after the fact, Marbles, too doesn't show much corpses for too long, you get the point.
Season 2 has Red Light Green Light too, but, the next game, Six-Legged Pentathlon, has the track covered in blood at every stop. When it's time for 456 and his gang to play, every single stop is covered in blood. Same for Mingle, the clean-ups are crude and the white floor outside the doors is left stained red. There's even a scene which shows Min-su stepping on a pool of blood and looking shocked, it's an omnipresent reminder of just how many people are getting slaughtered.. This time Special Round is never cleaned up because of the insurrection, and another thing I might add is that Jung-bae's death plays into this, kinda. Gi-hun is left kneeling over his dead body screaming, and the guards intently shove him down to make him spend longer staring at Jung-bae in a pool of his own blood.
I'm not a good theorizer but is there potential themings here? Or am I being dramatic?
