I had expectations about that this movie will be something extraordinary - based on the reviews. It's a bit slow when it comes to developing the storyline. Some moments are predictable,but also leaves the viewer in doubts. As a story - nothing new,unfortunately,just a bit more sci-fi coated with drama,some more physics to make it more mystique and high level. Acting is quite good,but the Texas accent of Matthew McConaughey is spoiling a bit. In general - it's worth watching,but won't make you ask yourself "what if?". If you like relativity and "save the world" movies - it's a good time waster. Still a way better than the most popcorn movies released lately.
