I am at a loss to understand why so many people liked and reviewed positively this movie. I find it scandalous that it appears to have more positive reviews than Gravity by Alfonso Cuarón which is a giant compared to this dwarf, in all aspects including acting, story line, dialogs and the visual effects. The performance of all the actors is average but the mumblings of the main character,Matthew McConaughey, are so incomprehensible and annoying. The computer graphics always play a big role in a science fiction movie. Unfortunately the director failed even to capitalize on it and the resulting visual effects are just average. In short, please do watch this movie if you want to see for yourself how a great amount of time, energy and money can be spent to insult human intelligence in guise of science.
