Interstellar spoilers:
I was debating 6 or 7 really. I liked the modern twist on the Dust Bowl era and most of what else happens on Earth. But then I found their insistence on hitting up the big tidal wave planet to be an unrealistic decision. I enjoyed their interaction with relativity there, but there really needed to be a more compelling reason provided for them going to that planet.
But then I really enjoyed the twist provided by Damon’s character, and the father-daughter reunion at the end. I think the idea that McConaughey went back through space time to save his family was a great plot point that was sadly very poorly and lazily executed. “Future human generations created this five-dimensional space for you.” yeah, sure. So why didn’t they all die in Dust Bowl 2.0 the first time around then?
