Anurag has a very good review of Nanni Moretti's "The Son's Room".
I love Moretti's films. I can see his films just to enjoy the use of natural sunlight. But I especially love "The Son's Room". It may be sentimental, but there is not a single frame of untruth in it. Isn't this how death comes into our homes: all too suddenly and cloaked in tragic illogicality?
To see how different film-makers handle similar situations and themes, compare this film to "In The Bedroom". (I enjoyed that film too, except for the resolution.)
