I just rented The Road. =/ Children of Men soon, too. I'm still trying to process the game after completion.
I haven't seen either before, but I'm going to watch The Road tonight.
Just read the book. It's very short, concise, and takes a couple of hours to read. This is the opening paragraph:
When he woke in the woods in the dark and the cold of the night he'd reach out to touch the child sleeping beside him. Nights dark beyond darkness and the days more gray each one than what had gone before. Like the onset of some cold glaucoma dimming away the world.

In the dream from which he'd wakened he had wandered in a cave where the child led him by the hand. Their light playing over the wet flowstone walls. Like pilgrims in a fable swallowed up and lost among the inward parts of some granitic beast. Deep stone flues where the water dripped and sang. Tolling in the silence the minutes of the earth and the hours and the days of it and the years without cease. Until they stood in a great stone room where lay a black and ancient lake. And on the far shore a creature that raised its dripping mouth from the rimstone pool and stared into the light with eyes dead white and sightless as the eggs of spiders. It swung its head low over the water as if to take the scent of what it could not see. Crouching there pale and naked and translucent, its alabaster bones cast up in shadow on the rocks behind it. Its bowels, its beating heart. The brain that pulsed in a dull glass bell. It swung its head from side to side and then gave out a low moan and turned and lurched away and loped soundlessly into the dark.
