a reluctant hero becomes a midwife

Rating: 5/10 (4 June 2007)

I've seen there are are 11 pages of reviews of Children of Men already. So, is there anyone who hasn't seen this film yet? As most of the reviews say this is a film about a dark future set in 2027 with life apparently changing in 2008 when people are unable to have babies. The film has lots of chasing about and fighting and Clive Owen as the reluctant hero drawn in to help an illegal immigrant who has somehow become pregnant.
It makes some comparisons with todays issues around illegal immigrants. All the acting is fine as everyone else says in their reviews.
I just don't get the logic of the film. In the future, the near future, something happens that prevents pregnancy across the world. Inevitably this would mean the worlds population would decline rapidly. There is some issue about Britain being a place worth getting to; I missed what that was about but somehow Britain is overcrowded with a Police state trying to keep out the others.
Surely if mankind is disappearing resources INCREASE for anyone that is still alive; no need for fighting and squabbles, no need for concentration camps at Bexhill, no need for police state. A sort of heaven for the 50 or so years until the last person kicks the bucket. Admittedly with too many resources and no competition for survival it might be as dull as living in New Zealand. The more interesting tale would be how the very last person does whittle away their last few years.
I guess really this is just a film that is meant to illustrate the reluctant hero in the ordinary man and maybe the extra ordinary event that is childbirth?
