Is Avatar culturally meaningful? Or just ridiculous? Sam and Vulture film critic Bilge Ebiri debate James Cameron's decades-in-the-making sequel and whether it's worth the hype (besides the whale part, which we've heard is cool). We also ask comedian Niles Abston if he is into Dave Chappelle bringing Elon Musk on stage as a surprise guest. And we hear about the culture that's haunting us: "Sir, sir, sir, I love you. I want to be your best friend. I should probably learn your name."
