Arkadaş is a very didactical film interwoven with dualist expressions and streotypes. Characters lack in dimensionality. Scenerio is weak. However, shooting a political movie in Turkey, especially in those times; 70s, required courage. Yılmaz Güney impressed me for that reason. If you want to sense zeitgeist of the leftist politics in Turkey, you should watch Arkadaş.
A Turkish man of the people visits a friend from years before and exposes his rich, bourgeois life for the empty shell it is, by showing him the misery, hardships and paradoxically happiness of the people outside his privileged lifestyle. Reminds one of Pasolini's 'Theorem' without the catholic guilt and an added dose of melodrama. Interesting mix of eastern and western film styles.
