It was awful, absolutely pointless. Without any drama that we can expect from this kind of directors, Nolan tried to make you excited by visual effect and music but these tricks! also doesn't work. We can clearly see everything comes from market: last year Gravity made and worked and Matthew McConaughey comes to media because of one successful series and film and today these two come together for more profit, or to just save the humanity :)) It's very funny and this film received high points because it can't even entertain you. I think generally saving the world idea like this film is bullshit and wasting the time but i diet think that it can be successful jet in box office like this. Don't waste your time and don't engage in fake world.
