You have to respect a horror film that really considers the biology and implications of their conceits. Zombie films, in particular, tend to be rather silly, even when fun. It has been a long while since I’ve seen a world where the science was derived from real life and thought through to give us a plot. Think 28 Days Later or Pitch Black (or even to some degree The Great Wall). Girl is a plague story with planned and realistic motivations, and with a script that doesn’t insult the viewer. In fact it goes places and considers issues with an incredible intelligence that belies its gory genre.
At the head of it all is the diminutive Sennia Nanua in her first major role. Expect to see more of her. She is confident and layered in her performance in a way that few young actors can achieve. She is supported by a talented adult cast as well. Paddy Considine (Miss You Already), Gemma Arterton (The Voices), Fisayo Akinade (Cucumber), and Glenn Close (The Great Gilly Hopkins) round out the main cast and become Nanua’s way to understand her world.
I have to believe that part of the reason for the success of this picture is the wide range of material under the directorial belt of Colm McCarthy. He does a great job of revealing the world and focusing the performances for Carey’s adaptation (of Carey’s own novel), navigating the genre without losing its humanity. McCarthy also understands the rhythms needed, keeping the emotional intelligence and human moments suitably calm so that the explosions of violence have impact. Even where it is predictable it is often unpredictable or satisfyingly complete; it never feels cheap. It is a rare that a director doesn’t give in to the histrionics and clichés in established horror tropes.
If you are looking for something fun and intelligent, this is your bowl of popcorn. It is full of action as well as thought and is every bit as good as you may have been hearing. If it weren’t for the genre, you’d probably have heard a whole heck of a lot more about it.
