TIFF Movie Reviews: The Buzz on This Year's Huge Films

Matt Damon-on-Mars is the biggest crowd-pleaser of TIFF so far. Damon is funny and engaging as Mark Watney, the astronaut accidentally left behind on the inhospitable planet, and the movie switches back to the other characters concerned with his welfare often enough so you don't also feel trapped on Mars. The movie's greatest success is making all of the science and tech speak accessible, even if you're not a rocket scientist.
