The CinemaSins team is joined by Neil DeGrasse Tyson, who’s here to celebrate The Martian even if no one else will.

Based on the best-selling novel by Andy Weir and nominated for an Oscar, The Martian achieved something incredible: It made astrophysics a pop culture phenomenon. For a while there, we were actually able to nerd out about science while reporting on a movie, and it was glorious.

Although the excitement for The Martian has died down, we can of course still talk science. And who better to lead the way than Neil DeGrasse Tyson, who also helped promote the movie via TV spots?

CinemaSins’ Everything Wrong With video for The Martian features Dr. Tyson — who is not here to blow apart the movie’s scientific credibility like he did for Gravity. Nope, Tyson is a total fanboy. Enjoy:

Of course there’s the usual callings-out of clunky exposition and characters acting for the sake of plot, too, as has become CinemaSins’ staple.

“Movie attempts to make botany cool” hardly sounds like a sin in our book though, and clearly, Neil DeGrasse Tyson agrees.

“The Martian, where fluency in science, engineering and math rule all decisions of survival,” he proclaims, interrupting the sinning. “Where science, not human emotion, drives the plot’s humor, interpersonal relations, tension, and suspense.”

And what makes this all even more awesome? “The Martian may be the first sci-fi blockbuster ever in which nobody dies.”

At the end of the day, there aren’t many legitimate sins left (we’re not counting the times the movie writes State names on the screen, or allows the Chinese to actually be heroes, because them ain’t hardly sins, CS), after Dr. Tyson has had his say.

After all, no movie is without sin, but making science cool, and “getting crucial science right” — that’s enough reason to celebrate The Martian!
