For the 1 star ratings...

Rating: 9/10 (4 November 2008)

I am extremely surprised to see that there are so many people who give this movie a one star rating. I suppose this film is a "marmite" film - either you love it or you hate it.
What the negatives fail to understand is that this is Hollywood Filming and we don't need all the questions we ask answered. The movie itself starts off by stating that there's nobody left on the planet under the age of 18. It doesn't answer why this is the case, and I think all the better for it. If they did answer it, the film would have no plot at all. Films are here to entertain us and make us think about certain situations that could arise and how the world would react to it. Although the fact that there's no children at all in the world may seem far-fetched, but we're supposed to believe this is the norm because that is what the narrative tells us to believe. The film's description says that there's no children left on earth, so you go into a cinema full well expecting that to happen and not question it. So if you don't believe it, it's your own stupid fault and have no reason to bring that matter up.
As an overall film, this is a great film. A powerful cast brings a realistic performance that is incredible in every aspect. Michael Cain's performance is legendary, he really does fill it well. I won't go into the film as a whole, however, since this really is one of those movies where you have to watch it through without any hints towards the events that follow. The only real concern I had was that I wasn't exactly sure why they decide to leave the country in the first place, but I probably overlooked that bit whilst watching.
Overall, a great film - definitely worth seeing.
