Finally a good film about the true story of Vajont: a very big landslide fell into an artificial lake causing an enormous wave (about 200 m tall) that went on the opposite side of the valley and over the dam, wiping out the underlying town of Longarone and causing more than 2'000 casualties in few minutes. The movie shows very well the intrigues cynically played by the construction enterprise to hide the dangers pointed out by geologists, about an ancient landfall line that the water of the lake made unstable. Well recited by the actors, the movie has good scenes, clever special effects, and a sweet love story within. It deserves to be seen; vote 8.
