The performances in the film are very high quality and the movie doesn't just focus on her main hits, it also shows her earlier music which has an Alanis Morissette quality to it. Her earlier music is actually very good and it would have been very interesting to see where her career would have been now had she been allowed by her record label to continue to pursue that alternative style. Through the course of the movie you get to see her triumph over all of these obstacles no matter how big they are and she becomes a better person because of it. You get to see her perform on stage in front of 10s of thousands of people, backstage during rehearsals, and in the studio. The best performance of the entire movie comes in the form of Katy covering The Beatles "Hey Jude", and it is fantastic. It is the first time that I feel she was really singing in the movie and not just performing and it made me see how truly talented she is.
On a separate note, you also get to see how her marriage with Russell Brand erodes over the course of her tour. They start out being madly in love and she is traveling to see him in between tour dates and it just starts to erode away. He seems jealous of her success and all of the attention that she is getting and seems agitated every time that he is backstage with her. Thought he was a complete tool before seeing this movie and this movie just reinforced my opinion of him.
This is one of the better music documentaries that I have seen in some time. The movie really does reveal how talented Katy Perry truly is and show the great lengths she had to go through to become successful. Her performances in the movie are top notch and her stage presence is ridiculously good, as she commands the attention of tens of thousands of people at a time. If you are a fan of her music or her boobs (for the guys) then this movie is made for you. Stream this online or pick it up on Blu Ray, either way it is worth your
viewing time. I included her version of "Hey Jude" for your listening pleasure.
