Not recommended.
Issues noted:
1. There seemed to be a big whiff of moral superiority cast upon the characters at the top of the high rise who were clearly implied to be involved in human trafficking of the people in the basement area. This is abominable.
2. Choice made by the main character to re-enter the high rise made no sense - she makes things worse for the people inside, being the primary target herself.
Appears to support lawlessness so long as it's cloaked under a thin veil of morality. We know next to nothing about the people who are supposedly "pure"
