I, personally, loved the ending
it was a very cliche kind of thing
the symbolism
of somebody passing away and someone being born , but it worked and felt anything but cheesy and forced. it was dark, depressing, and frightening but with a slight brush of hope enough to make the movie a pretty accurate representation of human life externally and internally. In all it's grittiness , Children of Men is one of the overall best film which surpassed my wildest expectations and had more to offer than I could have ever hoped. Every single aspect of the movie was flawless, symbolic and about as perfect as a movie gets. One of my most memorable movie theatre experiences, right up there with the New World, Sin City, & Lost in Translation along others.
