Interstellar is so good, but what's interesting is it had a luke warm reception upon release. It only has a 73% approval rating on Rotten tomatoes, which is less than Ant-Man 2
It also did okay but not great at the box office, finishing in 10th place behind The Amazing Spiderman 2
It's been 10 years since it's release and it's now considered a masterpiece, among the greatest Sci Fi films ever.
Time does funny things to movies.
