The first episode is the strongest being very atmospheric with nice cinematography and color grading that isn't a lazy gray tone that the other episodes do. The isolation and growing fear is very palpable and the vibes is a mix of psychological and supernatural. It reminds me of a Junji Ito story that also had to do with peeping eyes and being spied on.

The final episode is straight up Backrooms: Korea with the newbie security guard getting lost in ASync and everything. That other security guy working there didn't try very hard to warn her, though she most definitely wouldn't have believed him anyways. Poor newbie. Kdramas don't do backdoor pilots, but this certainly looks like a backdoor pilot of a kdrama if such a thing existed lol.

The home shopping story and the convenience store stories were about not taking weird jobs no matter how much money is offered. Besides that as a common theme, multiple times the episode monster is a guy wearing women's clothes and make up. That transphobia is really outdated and really telling of the prejudice from the production.
