Take an initial listen to Fifth Harmony’s latest album, “Reflection,” and you might think that you’re listening to a compilation rather than a cohesive release.

The return of the boy band has been a long time coming. The Jonas Brothers look surprisingly clairvoyant and avant-garde, what with their quick rise and fall between 2006 and 2008. Justin Bieber followed soon after, and, now, the British are coming. Or they already came.

It’s October, which means that most of the new shows from this pilot season have premiered, some of them with extremely good numbers. There haven’t been as many early or memorable cancellations as usual. Could we be looking at a repeat of 2004, when such gems as “Lost,” Grey’s Anatomy,” Desperate Housewives,” “House” and “The Office” premiered?
