A terrible movie and a complete waste of time, unless you are a big fan of computer games such as Call of Duty World at War and Black Ops. It is an almost uninterrupted orgy of noise and screams. After ten minutes I was totally exhausted. The characters are completely one-dimensional. Macho men running and shooting at everything that moves. They communicate by cliche oneliners. The storyline is as flat as the heartbeat of a recently deceased person. After fifteen minutes or so, I was so bored, numbed and fed up by it all that I "switched off", crept behind my newspaper and left it to my son and his friends to complete the viewing. From behind the newspaper I patiently endured the endless string of gunshots, explosions and shouted commands. Do not be fooled: there's hardly any science in this fiction, it's just a "one-in-a-dozen" war movie. I cherished the silence as almost never before when at last the TV set was switched off. I couldn't have cared less if the aliens had won.
