Is Odysseus a Hero?

This week, Andy & Brendan use Christopher Nolan's recent adaption (the space that launched a thousand thinkpieces) of Homer's The Odyssey to examine whether the archetypal hero Odysseus is, indeed a hero or, as some of those thousand think pieces have posited, not a hero at all, perhaps a villain? 

What makes a hero? What unmakes a hero? Does storytelling require contextual interpretation, in the cultural/moral setting it was composed in? Do mores shift definitions of foundational concepts? How do different cultures classify HERO? Is Odysseus a cultural hero type or a universal hero type? And has Nolan provided the keys to his own undoing, in the striking translation liberties he took? 

Joining the thousands of years tradition of analyzing Homer's work... is two best friends doing a podcast. 

What do you think about this question? And, most relevantly, what can you prove or disprove about either answer?
