Interesting story well told. The ending simplifies the truth somewhat as it took a further 2 years for Pinochet to step down, and of course the campaigns were more complex - the 'Joy is Coming' (translated as 'Happiness is coming'in the film was only one element - although undoubtably an important one.

 But allowing for the need to produce a coherent narrative from a very complex reality this film does a good job of telling its story and giving a glimpse of what it is like to overthrow a totalitarian regime when the opportunity presents itself
