And here I am, recognizing some of the plot holes existing but Interstellar is one of my favorite movies of all time. I've watched it several times, watched the first 30 minutes 10 times, and cry most times I watch it all the way through.
Let go of trying to analyze the realistic-ness of the physics (even if it's in this list) and immerse yourself in the story, the moment, and I think the characters are actually very realistic.
