Nice directing , camera motion , animation , visual effects .. But The acting is not as good , Sandra bullock can not do solos , that's proved on this film . Great actor , no doubt in that but not a one girl show type , George Clooney is being the usual great and funny man , he wasn't acting though he was being himself that's all . The bottom line here is that : if you like to be amazed by high tech 3D stuff , and nice camera motion you are in for a treat . For me , I found the plot rather ridiculous , really it is a science fiction story that would creep the hell out of Isaac Asimov . It's pure nonsense to consider Space as a 1200 square mile big , where satellites are falling like domino ! For the characters they are so poorly drawn , Clooney's character has absolutely no depth , none .. Zip , even Sandra's character has very little depth that's poorly performed and written . So basically no acting and no story only fast paced action disaster movie with no solid plots that just happened in Outer space , only good directing and effects . This movie isn't remotely likely to make it to the classics wall . But that doesn't mean I regret watching it after all .
