I finally saw this movie. It's lengthy but worth the time.

Rating: 9/10 (3 November 2016)

Take your time watching this and pay attention to some of the minor details, they turn out to be major to the plot later on.
A future Earth has exhausted the quality of planet's soil because humanity became too numerous (more than 6 billion) and a former pilot, would-be astronaut named Cooper is directed to an old NORAD site where NASA has been sending probes and manned ships into a wormhole that opened next to the planet Saturn. He finds the facility with the help of his daughter, who has been making notes about gravitational anomalies in their home (books falling off a shelf in specific numbered places) and figures out they are given coordinates. These coordinates lead them to the NORAD site. Fast forward, he joins the next NASA mission which send himself and three other scientist through the wormhole to investigate a new solar system with many worlds that humankind might be able to inhabit, since Earth is dying. With their fuel, they can only explore three but these are three worlds where previous, one-way missions ventured to see if they were habitable. They come up short on the first world which has huge gravitational fluctuations because it's close to a giant black hole. They are then lured to the second world by an unscrupulous scientist who was part of one of the earlier manned mission to explore the new planets. He wants to leave and tries to hijack the main ship in orbit around his captive world, only to kill himself and damage the main ship. Using one of Einstein's theories concerning black holes, he is able to slingshot the damage ship towards the last world they can explore, sending one remaining scientist and a robot assistant on board to reach the third planet. Coop releases himself in another spacecraft from the main ship and flies into the event horizon of the black hole. There he finds himself in a strange room that seems made of lines but is really a fifth dimension where he can look through and see his young daughter on the other side of the bookshelf where books where falling. He recognizes that she is the same age and it's the same time as when she first told him about the books. He also realizes that it was HIM sending her messages all along. Beyond this point, I won't give anything else away and my hands are getting tired too. LOL! It's a very complex movie but rewarding for those who want to invest the time (runtime is 169 minutes) to watch. It delivers on a lot of logical, theoretical and emotional levels. It makes you ask the question, can those of the future help those of the past. There is a lot of paradox in this story, so be prepared for that and free up your mind, otherwise it will cook your noggin!
A solid 8 out of 10. It definitely pays homage to 2001, A SPACE ODESSY, at least in my opinion.
