It's not terrible by any stretch. It seems like U2’s tribute to other artists was lost on many viewers, creating the impression they were trying to position themselves alongside legendary figures in rock and blues when they were actually showing appreciation for their influences. I suspect the real point of contention revolves around Bono. People tend to either adore him, almost treating him as a deity within the realm of rock music, or dislike him intensely for that very same quality—his willingness to invest himself emotionally. This might be why so many viewers didn't connect with this documentary. However, it’s possible that criticisms stem from U2’s missteps later in their career. *The Joshua Tree* marked their major breakthrough, and a common sentiment among fans is that they peaked before achieving widespread fame. That assessment isn't entirely accurate; aside from the debate surrounding *Zooropa*, they maintained a high level of quality through the *Pop* era. More likely, the disappointment following *All You Can’t Leave Behind* and the subsequent underwhelming albums has soured people’s perception of the band. It deserves at least a brief viewing, as it functions as an expression of admiration for American music in general and the rock and blues icons who shaped one of the most significant bands of the eighties.
