This "Chained" is very well realized: you FEEL everything, you are there, spying the life of this man which is behaving in the most wrong ways you could imagine, without any help to recover.
So it is like a "documentary", perfect in its representation and in transmission of the tragedy, but...
I think that stories, and so movies too, should be better than life: they should give audience some directions to become better people, making see how a character could change his behaviour, his ideas, in order to quit despotism, machism, cruelty and egotism, reaching some empathy with all beloved significant others, wife and step-daughter.
Here we follow the tragical crumbling of the life of a policeman, which is obviously wrongdoing at many levels, professional, personal and sentimental... and nobody helps him.
So I think that this total despair is strongly wrong in a work of art.
