Not really, it just proves it is more successful in what it aims to do. Whether that means "a good film"... well that's debatable.
Interstellar has 12 rotten reviews out of 45, while Gravity has only 10 rotten reviews out of 305, proving that Gravity is a better movie.
It was a really well executed technical excercise but I can't remember much of it by now, to be honest. It had a really weak script, that one.
