The Boy Bands were basically, now that we get to really see what their only real talent was, barbershop quartets/quintets with drum machines manufacturing songs written by professionals... musicians other than the boys themselves, who were handed big deals but, so it seems in the case of The Backstreet Boys and NSYNC, their deals weren't big enough...
Making the most intriguing aspect take place during the first part in which we learn of the rise of these two very famous groups (on the heels of New Kids on the BLock) alongside their founding manager Lou Pearlman, who made money with blimps, or airplanes, or something...
It's after both boy bands sue the central figure Pearlman does the documentary get a bit dry and uninteresting, mainly because the leftover groups that Pearlman created never made any kind of lasting impression... in fact, they weren't even worthy enough to make fun of, and hardly even register on the pop culture conscience...
Since this was produced by Lance Bass, there should have been more info centering on those two big bands and Pearlman's connection with them, and then leave the last half of the third/final episode about all the people he ripped off instead of that stuff being dragged through one and a half episodes...
Either way, this wasn't a bad doc, and filled the time nicely... but didn't stick to the things that people would actually care (or know) about.
