By now, all the movie critics have had their say about Christopher Nolan's epic outerspace drama, "Interstellar." But if you're looking for a different kind of review -- one that rates the movie's science instead of its story, performances or camerawork -- then you'll need a different kind of reviewer. Enter Neil DeGrasse Tyson, who had some thoughts about the film's scientific strengths.

Let's start with the obvious: This movie is full of scientists.

It gets points for representation, too.

In "Interstellar," you can see the effects of gravity accurately illustrated.

A couple of Einstein's theories make an exciting big-screen debut, too.

But seriously, the gravity! This film does gravity like nobody's business. It's got better gravity than "Gravity.".

Then, it gets a bit technical.

Really technical.

But the science, at least, is solid.

The story, however...

And there's also the little problem of robot nepotism.

But Neil DeGrasse Tyson doesn't want to tell you how to feel about it. He just wants to talk about science.
