Children of Men has an absurd premise. In stead of depicting a world where human fertility has dropped significantly resulting in chaos, we are to swallow that 'over night' women stopped giving birth period (did the aliens from Worlds finally get it right this time?) and that the only country which can deal with this is Great Britain partially due to the introduction of a nazi-like regime. Why the rest of the world failed to do so is never explained just like everything else which is thought up as the storyline progressed.
The story which is served is equally as absurd as the premise. In a nutshell we are to believe that the birth of a single baby doesn't sound the dawn of a new age but in stead will lead to scientists implementing what 'naturally' happened to this horribly acted Kee on a global scale? This to further the idea that despite the self-destructive nature of humans we are still in control of our fate? Or the proof of the existence of God since it wouldn't be possible for ordinary people to stroll through a warzone with a freshly born child being shot at with endless rounds of amo and survive? Again, this is not explained in the movie, narratives were absent much like any memorable acting, the cameo of Caine aside.
The baby being born into the childless world has no real enemies, only the opposite. Yet it is being hauled through a warzone on a tip by a stoned and aging hippie whose purpose in life is to have his fart-finger pulled, in order to reach a certain group of people who's intentions remain completely vague throughout the entire film? Sigh, how utterly stupid. In 2027 there are only two boats left? One in a warzone and one owned by the 'Human project'? Sounds more like a video game to me, hardly like the story of top-rated movie.
No plot development, no character depth, serious low-budget-feel cinematography and a script without any poignancy. Nothing in this movie that would make it worthy of its high ranking. Totally out of place action-shooter war-scenes and the cheap Hollywood appeal on the senses which initially seemed to be left out, magically appears (alongside the terrorist cell) during the urban shoot-out and henceforth during the so called ending of this movie. The boat being called 'The Tomorrow' came straight out of the Shallowwood textbook and made me bite my teeth till they finally broke off one by one.
The poorly developed chase story which CoM basically is, is just too one-dimensional and frankly just straight out flimsy and it got boring fast. And it is so filled with implausibilities that even the greatest mathematicians of our present world will not be able to count them all.
