THIS MONTH’S THEME is Irish horror. And it’s not all Warwick Davis cackling about his pot o’ gold. Kate Dolan’s You Are Not My Mother is an outstanding mix of North-Dublin-housing-estate social realism and faerie legend. Teenager Char (Hazel Doupe), tight-lipped or seething with pain, worries that her bipolar mother Angela (Carolyn Bracken) has been replaced by a vindictive lookalike out to punish her family for a past transgression. Char also has trouble with a local girl gang who are collecting scraps for a Halloween bonfire that’s sure to feature in a last-act ritual. Like several recent horror movies (The Babadook, Relic, Antlers), the underlying subject is living with a relative who’s struggling with mental illness, but this doesn’t neglect the supernatural horrors. Doupe and Bracken are awards-quality brilliant.
