Probably from around 2010 or later. American or Canadian, probably. Protagonist is a misfit girl with a dead-bunny style hoody I think. Her mother disappeared years before, there’s an underground fungal mega-organism under the graveyard behind her house. Mom’s down there, dad gets taken, and then her lil bruv. There’s a shot of her sitting on the room, looking bored as black slimy tendrils grow up around the house and she gets ready to fight. Thanks in advance!
