I can see where you formulate that opinion. . . I don't know. I think that he was trying for a Kerouacian sort of stream of conciousness and seeming lack of editing, and I think that muse didn't fail him, I think he succeded. And I think that the Swiftian nature of his mean-spirited lyrics lifts them somehow, they're poignant rather than being arrogant. Just me I guess.
Also, from what I have heard and seen of other interviews and these in the documentary. . . .Seemed more liking tilting at windmills and being very clever and quickwitted than narcissistic and repulsive to me. And I love how he refuses to buy into the methodology and intent of the press and jousts with them instead. High entertainment!
