There's a starman waiting in the sky, and his name is Mark Watney. Back in February, we talked a whole bunch (some would argue too much) about the Red Planet's greatest botanist when we hosted a Gobbledy-Book Club discussion of Andy Weir's The Martian. Now, Paul and AJ have reconvened the Book Club--Wanna Cook? author Ensley F. Guffey, So Let's Get to the Point's Kenn Edwards, and the all-around amazing Hallie Prime--to tackle Ridley Scott's star-studded film adaptation. Is there a certain amount of character-building shorthand a filmmaker can accomplish by casting familiar faces? Is the film really the story of a band of precocious potato plants? Does Matt Damon have the chops to be stranded all by his lonesome? And most contentiously...does the science hold up? All this and more, plus what pop culture the gang is excited for.
