Interstellar's intense focus on realistic physics was such a breath of fresh air. It was just such a good movie. I desperately want there to be a sequel of equal or higher quality to find out what happened at the end of the first movie.
I have only one gripe here in that although they consulted with Kip Thorne at Cal Tech, they took artistic liberties beyond his black hole research and theory.
Yes, the film seems like the physics are all real, but they aren't. How about the anti-gravity drive on the lander ship? Somehow the ship possesses this magical tech that can fly them off worlds with ease yet they had to use regular rockets to launch the original mission into space. That's a huge break in universe continuity and has always bothered me. The time dilation stuff, though, is pretty awesome.
The ending with the black hole communication was also artistic liberty.
Great film, otherwise, and has an awesome message.
