This is a solid horror film full of cool coloration, shadowy lighting, funky close-ups, loud noises, a relatively idiosyncratic soundtrack, and some genuine drama thanks to an excellent performance by its lead. BUT — that doesn’t mean it takes itself seriously. I had some initial concerns about how hard this movie hits the gas pedal.  We aren’t really given much exposition before the action actually starts — and when the motives of the antagonists start trickling in, I find myself wondering, “What? Seriously?”  And I won’t spoil anything here — but... no. 
It’s not a serious film. 
Walk in to this one ready for anything — except tons of “scares” (but what are scares really?) — and you’ll have plenty of fun with it.
