I really don't want to enter this fray. But for those looking for an informed review of the film, I'll offer up this review from "Reverse Shot."
They rated Children of Men at #19 in their "Best of the Decade" review. Their review brought me back to an appreciation of good criticism, whether pro or con, that doesn't limit itself to an academic interpretation of how well a film conforms to certain preconceived "rules" about how a film should work.
Here is their comment on the opening take, plus much more at the link.

Defying expectations, the clarity of Cuarón's vision was apparent in the movie's opening frames.
With stunning confidence, he thrusts viewers into a bleak future: over a black screen, we hear a news broadcast that leads with a story about the death of the world's youngest person—an 18-year-old. Cuarón cuts to a high angle shot of a crowd of people in a cafe, transfixed as they watch the terrible report on a television set. Theo enters and orders a coffee. As he looks up, Cuarón cuts to the monitor, then back as Theo gets his drink and leaves. The camera follows him in a handheld shot out the door, pausing to take everything in after it exits to the London street (a subtitle reveals the date: November 16, 2027).
Cuarón's camera turns towards Theo, walking with him and then stopping when he steps aside to add some booze to his coffee. Then there's an offscreen blast. The ringing of Theo's ears takes over the soundtrack as the camera turns back and moves towards the smoking cafe, out of which emerges a woman charred from the explosion, carrying her own arm. The sequence is shocking, even grotesque, but in its narrative efficiency and strict attention to point-of-view it prepares us for the unrelenting cinematic tour de force to follow.
Missed this back when you posted it, but thanks for doing so. That was a great read.
