Part biography, part concert movie, the film follows pop singer Katy Perry on her 2011 Teenage Dream world tour which proves a massive success playing to sold out arenas ... meanwhile her personal life deteriorates as her marriage to Russell Brand falls apart. One's enjoyment of the film is based on one's like of Katy Perry. If you're not a fan, you're probably not even reading this, much less interested in the movie itself. As for me, I'm a fan of Perry's irresistible catchy pop tunes like I Kissed A Girl, Hot N Cold and Firework, appealing personality and legitimate pop voice (the gal could do Broadway without a problem) so I had a fun time at it. Once again, 3D is foisted upon us when it adds nothing to the project except in some of the concert footage. Perhaps the most interesting aspect of the documentary portion is Perry's upbringing as a Pentecostal Christian and early career as a gospel singer and her breaking away from the restrictions of that life. Directed by Dan Cutforth and Jane Lipsitz.
