One of the better Sci-Fi moral/relationship stories

Rating: 10/10 (17 March 2015)

I just watched the movie "Interstellar". Awesome movie. It was a tear jerker for me. It had a daughter/father thing going on, which most of you wouldn't know about that type of situation. I wasn't merely having tears, I actually started bawling for at least 3 points in the story.
It had a good time paradox thingy going on as well. Powerful story concept if you have an open mind to the possibilities of our actual existence in this universe.
Great acting in all characters. Kudos to Matthew David McConaughey, Mackenzie Foy, Jessica Chastain and Ellen Burstyn. The other actors also did a great job.
OIf course, there is also the moral dilemma of what to do when trying to save the Earth and, more personally, we humans.
The only issue I have is... Who are "they"? No depth at all into that. I think we are supposed to create our own "they" this story. Either one we pick, the story of this movie fits.
One of the few movies that has actual meaningful depth in its overall story.
