It is true that both seems to be looking at their creator when Page does Whole lotta love, but along the movie both White and the edge have no complex what so ever. Particularly Jack White, whose coverage seems better than the one on the Edge, is quite proud of where is coming from and it still defines his music.Don't think he was really criticizing the Edge's playing; but the fact he just wasn't a good interview - too quiet. I also read the director of the film was just over the moon that Page wanted to cooperate since he doesn't do many interviews! The other 2 guitarists from what I read were in awe to see him jam on some of his old riffs like "Whole Lotta Love"; which he said "isn't as easy as it appears".
