Interstellar > The Martian

Because:

• Matthew Mcconaughey > Matt Damon
• Evil Matt Damon > unbelievably-resilient Matt Damon
• Saving the world > staying alive
• Alien planets > Mars
• Physics > Botany
• General relativity > laws of thermodynamics
• Relative time > sol (Mars day)
• Expressing struggle through emotions > through fun & jokes
• And also because of giant waves, black holes and wormholes
