While watching Katy Perry: Part of Me 3D, there's no way you won't feel apart of it every second.  The movie was all about Katy's life, how she got her start, the hardships she went through and where she is now. The movie was very touching and like being at one of her concerts. I loved the way you really felt like you were there and all the touching stories. This movie is really good for any age group, even little kids! I give it an A+, it's a definite PICK!
