This Greek film is definitely from the Michael Haneke school of film making. Odd angles, lack of ambient music and lack of a colour palette at times.
It's a very sterile film in both subject matter and visual style. A middle class married couple keep their 3 late teen children in virtual isolation from the outside world and even assign different meanings to some everyday words to seem to keep them safe from any of the ills from the outside world but of course biology takes it's course and violence on an incremental level and sexual awakening come to the fore.
In fact I absolutely hated this film on one level as it's fairly disjointed story wise and seems to revel in it's cold, clinical approach to the characters but there is also no doubt that it is an intelligent film that poses serious questions about protecting people from the world but ultimately this overbearing stance is not always the right thing to do.
I just about got through it but doubt it if I will watch it again.
