I think what I love the most about this is just how grounded and real it feels. I went into this expecting typical horror movie tropes like the office guy suddenly dying cause he was in over his head on something, but surprisingly, he acted how I would expect someone experienced in dangers of the foundation to be. He knew what he was up against. and how to navigate it. He only truly got terrified when something unexpected happened, and it shows in the fact when the security guard walked in, both me and him were expecting it to be the SCP featured here.
The presentation of scale and the aesthetics blew me away on this, can't wait to see more.
