This is a beautifully written, beautifully acted and beautifully shot piece of work. The understated performances from Colin Firth and Olivia Colman are a delight. This film captures the stiff upper lip, keep up appearances at all costs way of life with the real emotion always simmering beneath. If action movies are your thing you probably will not appreciate or make it through this film but, if you do, the rewards are bountiful. It is an absolute masterpiece of understated excellence.
