Superb. Realism gives way to horror almost imperceptibly in this Iranian production set in Tehran in the 1980s Iran/Iraq war. I won't bother getting into the plot, but it gets points for keeping the audience off-guard, fantastic sound design & visual sensibility and the great sets. Most of it takes place in an apartment and it's reminiscent of Repulsion in the way the interiors reflect the state of mind of its inhabitants. Really effective, even/especially without the usual SFX CGI bunk.
I loved that one.
Even without the supernatural element I thought it was a very good and rather tense war-torn family drama.
