Nowhere near the bullshit PR fluff piece you might expect. It's hardly investigative but it does paint a pretty multi-dimensional picture of Ms Perry.

The music is good and the stage show is spectacular so the concert elements are suffieciently fulfilled. As a look at her life off-stage it's surprisingly touching as it fairly candidly deals with her marriage breakdown and, y'know what, just a little bit inspirational in its retelling of her struggle to reach where she is now.

She might overplay the lovable freak routine a bit but her dedication comes across without feeling like she's playing up for the cameras.
