A concept film where, really, there’s barely any concept and virtually no action, just a man in a car, driving in the night and talking to people, desperately trying to keep his world from unravelling. And that’s it. The chances of this being a good film may appear slim, but it really works tremendously well. Inevitable plaudits have to go to an excellent performance by Tom Hardy, although the script and pace are also magnificent. Not a comfortable watch and not for everyone, but this is really compelling stuff.
