This was also my first real experience of Antigone. I'm pretty sure I've read the Wikipedia summary at least once, but this was still effectively blind. It seems like a very worthy adaptation.
(I am, admittedly, largely taking it as a caution against living in an apartment with so much mold and possibly heavy metal contamination that it gives everyone a mental health crisis. Side effect of the remarkably clever idea of making them landlords.
...and also of adapting the presumably-traditional ending, rather than "hello, fire department? So, my uncle has barricaded everyone inside the building, and promised to kill me if I bury my dead brother. Can you come break the door down?")
