Interesting story I had never heard
I wish the movie had shown us more about his background so that we had a better idea of where he was coming from, of his motivation. 7/10
There were a couple inaccuracies. He and his wife did not split. She was with him until the end. Re the attempt to shoot down a plane in Rome, in real life he did not sabotage the equipment. Instead he simply called the authorities on the guys.
