Went to see it on Sunday and it's excellent. Well worth seeing. Essentially a lot of it is barely fiction but I think if anything the experience of being IN the darkened theatre rather than the crowded train hits home a little harder the feeling of what war is or might be like. Its pretty funny in places too if you can manage to laugh at such dark and worrying matters. There is a review on culturevulture that i think is relatively balanced. Better still why not go along yourself? Tickets can be bought online here.
