Query: Its what you expect

I'm not sure of the origin of this video, but it definitely feels like an MTV or VH1 produced 1-hour bio.Katy herself does not appear or endorse, and the talking heads comprise the like of the L.A Times editor etc...If you are a fan, then this is worth the $20. You get a pretty decent look at her past; there was plenty of new info about her that I never knew.I would liked to have seen more clips of Katy, esp behind the scenes or of her private life, but for what it is, an unendorsed biography, its not bad at all.
