I wholeheartedly recommend this film.
It is a thought provoking piece of work which should also encourage watchers to find out more about the middle east crisis.
Politics aside, it is visually wonderful and I agree with your reviewer that animation somehow allows the filmaker to give the dream, flashback and hallucination sequences more emotional resonance.
The soundtrack is judged well. My only negative comment is that the ending jarred. The film was very emotional and unsettling and the final scenes were not needed to underline this. It's almost like the filmmaker lost confidence in himself. He shouldn't have done.

Without a doubt the most extraordinary and moving documentary film I've ever seen. It left me speechless. Please see this film if you have the chance - it speaks about so much more than its immediate subject.
