The film had some good special effects and an enjoyable dystopian theme, but it was nothing like as good as it's hyped up to be. Much of the dialogue was incomprensible mumbling, especially by McConaughey, and I eventually had to turn the English subtitles on to see what was being said. The biggest issue with the storyline is that nobody would seriously think of evacuating humanity from Earth under the circumstances depicted. Also, the idea that Earth's atmospheric Oxygen level could drop by any appreciable amount is simple unfeasible, no matter how much we screw up our only home's natural resources and climate. And it's not as if those potential new places for people to live had breathable atmosphere anyway - the crew still had to wear spacesuits all the time there didn't they?.
