I'm REALLY late on this. But I finally got around to watching it. I think it was equal to 2001, but in a different way.

In the movie there was a battle between two ideologies: Survival as a species vs survival as an individual. 2001 was about our species. Evolution was the theme. 1st as hominids discovering tools up to the birth of the star child.

Interstellar showed that an individual can survive what it would take to reach the stars and touch the inexplicable.

Interstellar was good, but it was like the Kidz Bop version of 2001.

I have to disagree. Interstellar paid more attention to detail on the science side of things than 2001 did. It was just focused more on the human condition. Above all else, Clark was a futurist.

If anything, Nolan was showing us how WE fit in 2001. The plot lines are pretty similar when you take out the plot devices. 

2001 had immanent nuclear war with Russia. Interstellar had ecological collapse. 2001 had the First Born and the Monoliths. Interstellar had 5th dimensional beings communicating with gravity.  Bowman and Cooper both overcome a mutiny that take their crew and go on a hero's journey through a singularity. The movies end with humanity either evolving or being directed to evolve.

The difference is the focus. 2001 was about the species as a whole, Interstellar was about the individual. 

the end of the movie really kills it for me
all the 4th dimension bullshit
