Fabulous piece of work by all concerned. We get to see all sides of a single story without excessive back flips, cartwheels and other cinematic tricks. Coogan has got the measure of this story and pulls off a truly convincing performance as Sixsmith whilst Dench almost manages to do an entire film with a dialect....occasionally lapses but you may not notice. This is a real tear-jerker at points, thought provoking at many junctures and full of ironic humour. That's quite a feat and the more enjoyable for being so. I presume the timescale is roughly ten years ago so attempts at getting tech right for the period is still possible - amazing that so recent history can seem like centuries ago when we see old technology in use. I can see this film being a 'classic' long before it reaches any real age. Its the 21st century version of a 19th century Dickens tale, that it is.
