The family and I finally saw Interstellar (2014) a few days ago. I'm sure this bit is probably the part that gave rise to the most negative hits in the reviews ("oh, great hard sci-fi, great special effects, but what was thaaat?").
Too short a clip to be a spoiler, I suppose.
Forget those reviewers. Best part of the movie, I say. Or, rather, I said? Those specific ideas have been rattling around in my head for the past few years, is what I'm saying.
