I really enjoyed it. Especially the very big chaotic scene towards the end. It was planned and shot very well.
I was also a very big fan of Picasso's Guarnica in the background of his cousins office.
I liked the film so much that I started reading the book about a year and a half ago. But thanks to school and stuff, I was taking a literature course that was requiring me to read several novels, I never finished reading children of men. Its still sitting in my office room. There one quote I love from it in particular and I see I actually placed a bookmark at it:
"Now for the rest of our lives we're going to be spared the intrusive barbarism of the young, their noise, their pounding, repetitive, computer-produced so-called music, their violence, their egotism disguised as idealism. My god, we might even succeed in getting rid of christmas, that annual celebration of parental guilt and juvenile greed."
with that it became very clear to me what the book was really about. The young were savages, they used their strength and ignorance to their advantage.
I don't remember if they specified or not in the movie, he hated his daughter. She was ugly, looked like a version of his crusty old father-in-law with pig tails. One day he accidentally ran over her while pulling out of the drive way. Thats how she died. How tragic that suddenly people wouldn't be able to have kids anymore.
