It's far too long, the story is confusing, and the love affair is unconvincing. Ingrid Bergman is lovely, but her character is incredibly irritating. There are a few good scenes, but they don't make up for the rest.
Quite an endurance test this one. Cooper and Bergman strive very hard, and do their best, but the plot lasts for 153 minutes, which apparently was very much reduced as time went on. When you consider that the main reason of the plot was to blow up a bridge, it did take an awfully long time to press that button. However the instant love plot between Gary and Ingmar adds a bit of fire to the story, but even this seems never to have been consecrated. Yes, a long piece of cinema, a bit like this review.
