You know, I've been silent on this thread for quite a while, but I've heard and seen other mentions to this movie.
I feel like the only person who saw the movie and thought that while it was not bad as a movie, it was incredibly stupid and unrealistic in its portrayal of human behavior. It erred both in its pessimism - the behaviors depicted in the movie are plausible and people have done the same and much worse, but not for the type of reasons depicted - and its optimism (esp. the scene in the end where the fighting stops because of the baby).
My main issues with the premise are the following:
- People adapt to new situations far quicker than the movie assumed. If, indeed, all human reproduction would suddenly cease, people would be deeply disturbed for a few days and return to life as usual within a few months.
- If there were no new babies, then population levels would start dropping. There would be less competition for resources, not more. Within a decade, most of the poor parts of the world would be less poor, and there would be less immigration pressure, not more. There would be a problem again in 50-60 years once the population capable of doing physical labor becomes too small to be managable, but at the timepoint depicted by the movie, things would have still been fine.
Since I couldn't buy the premise, I couldn't invest any emotional depth in what was happening. The movie felt to me as silly and artificial as the latter Die Hard movies. Passable entertainment, yes - but why a lot of intelligent people seem to think it shows any level of profundity I have no idea.
