It's 84 minutes, so it's unlikely any of us is going to watch it, beginning to end. But there's an interesting part up near the front, where he says, "In the US, irony and humor become a political response....Irony and dark humor can be a way of— it's protesting when it really isn't. Someone once said 'Irony is the song of a bird that has learned to love its cage.'" What a great, true statement.
There's also a great part where the cameraman says some very stupid things that you can just feel are very upsetting to Wallace, but he's too polite to react badly to what are unintentional insults. But I'm not saying you *need* to watch this. I just think it's a really interesting interview, warts and all.
