The characters werent very likeable, especially Pegg who goes through the whole experience and comes out on the other end with zero growth, if anything, its a massive step backwards for him, while his friends who he abandoned when he was young grew up, he stayed a manboy, with the same clothes, the same car, the same music, and he ends the film with the young robot clones of his friends, reliving his youth forever more.
The film ends with all technology destroyed and earth back to the dark ages, yet despite no commincations whatsover, and only one small villiage in england being taken over by the blanks, everyone everywhere seems to know about them, purely by word of mouth from the handful of survivors.
Not only that, but in a world with no money, electricty, or running water, people are still buying houses?
