I think this film is "a peace message", the film director show us an ideal future of tolerance and peaceful coexistence between Israel and Palestine.
This absurd matter is tell by a metaphor of two boys that were exchanged at the birth,the palestinian live in a jew family and the jew live in a palestinian family,then casually they discover the truth.The plot is simple and foreseeable,the characters aren't realistic. All solve in a not believable way and without any sense of tragic.
I think the message of this film is very important,but it could be well.
