Anyone will enjoy it, but those with an understanding of Jewish rituals and customs and Israeli culture will really enjoy it.
I'm not sure what the directors/writers major message was, but my interpretation is that:
You can't escape your past and who you once were, but you can learn from it and use it to help you reach greater heights.
there's one telling line in a movie that resonated with me (paraphrased):
Man thinks that when he has worked hard, he has earned a rest. The fact is, when he has worked hard, he has just earned a much larger test. There is no rest.
