The Greek civil war (1946-1949) is a taboo for Greek cinema, and Voulgaris in this film treats the subject attempting some form of reconciliation. His heart "beats on the left" (whence the title, "Soul Deep", which was a greeting amongst rebels during the civil war), but the film does not deal with the deeper reasons behind the events. He blames the Americans and the Soviets who fueled the conflict and then abandoned the Greeks to a political chaos and a tragic civil war ("this is not a war, this is a disgrace", says Thanassis Vegos who comes to seek the body of his dead grandchild, so that he can bury him) that led people form the same village killing each other and former friends, even brothers (like Anestis and Vlassis who fight on different camps), becoming enemies.
Pantelis Voulgaris surprises us by filming with great lyricism, stunning cinematography, and at the same time a with a decent sense of rythm (and that's surprising) in the action scenes. Sometimes, though, things get too melodramatic and this may bother some (it did bother me).
What really amazes, though, is the incredible soundtrack by Giorgos Aggelakas. Modern, yet blending perfectly with the subject matter and the cinematography. If for no other reason (and there are plenty of other reasons), it's worth to see the movie for its soundtrack alone.
