The Promise (2017)

A ghost story with a real economic wound at its core. Sophon Sakdaphisit, who co-wrote Shutter and Alone, sets it in Bangkok after the 1997 Asian financial crisis: two schoolgirls make a suicide pact, only one keeps it, and twenty years later the debt comes due. The film was shot in an abandoned, unfinished skyscraper left over from that crash, and the empty concrete floors do half the work. It is more about friendship, guilt and inherited trouble than shocks, and it was chosen for a Thai horror season at Melbourne's ACMI. Ideal if you want horror that says something about the city it haunts.
