I watched it, and it was an engaging mix of lucidity, nonsense, insight, and delusion. Intended to be a 30 minute interview, Kanye had much on his mind, and they went for two hours. He wasn't clearly not himself; he's always like this during his public, manic phases. (He goes dark during his depressive phases.)
I think our society has gotten so used to pop stars who are safe, sanitized, vapid graduates of Disney kids, and "transgressive" high artists bravely fighting the against dead horses slain generations ago, that we've lost the capacity to handle artists who can be disturbing and awkward at times, and creatively redeeming at others, but can't easily be categorized as perfectly good or purely evil.
