Tom Hardy drives his car while speaking in what attempts to be a Welsh accent, on the phone. Nobody else is in the car and he never gets out of it. A lot of the conversation is about concrete. Olivia Colman gets to literally - lol! - phone her performance in.
It’s sort of quite compelling, in a strange way!
Amazon called this a “thriller” which I feel is more or less a complete lie. My wife gave up part way in, too annoyed, and I’m glad she did because the way it ends is very accurately the kind of ending that makes her very cross. Me and my dad were glad we stayed the course.
