As other reviewers have said, this is a profound and engaging film that appeals to both your head and heart. I won't repeat the plot, but it does a fine job of making both the Israelis and their targets human, fallible and empathetic. And in this lies the true tragedy of the middle east: that a man who can spent his time translating the Arabian Nights into Italian can also be a 'terrorist'.
In lots of ways I found this a difficult film to watch and that's as it should be. The violence, when it comes, is always profoundly shocking, as is the human cost. The deterioration of the moral sense is captured perfectly. But beyond all, the final question that the film poses is what should we do? Does condoning violence only serve to exacerbate it? If retribution only does the same then where are we to turn?
It reminded me in some ways of Sophocles' dramas, particularly Antigone where there is no right or wrong solution, only people caught up in impossible situations where the end-point is always death. And yet the very humanity in the struggle to negotiate the moral maze is itself hopeful and I think that's where Spielberg succeeds in leaving this film. So overall a very intense experience but one very worthwhile.
