Too complex to understand, McConaughey incomprehensible, too many unanswered questions. The script - storyline blew it on all fronts. Here's the way I wished it would have played out. Establish better setting & foundation. World's climate is changing for the worse, in haste and a means to provide hope, vast amounts of new money is granted into the world space program to investigate and explore an unknown anomaly (worm hole) found near Saturn. The first group of scientists penetrated it a few years back, disappeared from contact but somehow sent a successful radio signal back to Earth indicating they found something magnificent which would be considered one of the greatest discoveries of all mankind. Send in the next group of scientists (better equipped and better technology) to find out more about what happened to the first group. (You could have built an entire movie around that worm-hole by itself.) As they come alongside the worm hole, conduct tests, send in probes, then eventually manned spacecraft. Once inside the worm-hole magically transports to another galaxy and in close proximity of a solar system similar to ours of which there are planets that can sustain life. They find a planet there like Earth. Alien beings (smart and intelligent) welcome them to their planet. They find their comrades there in good health and well being. They exchange technologies and are told that a whole plethora of wormholes are all over the place in space but they need to be "opened" by some sort of gravity means. The aliens have perfected this. The aliens learn about the slow demise of Earth's atmosphere, they offer assistance. A few of them go with the scientists back to Earth and all is saved!! See? Now THAT would have been a better story than the Interstellar movie script.
