The story is really simple. Ichigo is planning and producing with her friends a festival with her name, so she has to search for a good song and a new dress. This time, is a good opportunity to see all Aikatsu characters all around at the same time. So, movie is set up between season 2 and 3, so new characters like Yuri or Madoka doesn't count.
Talking about the characters the only ones that have really development are two. The first one is Mizuki. In this movie for unique time we see what is afraid of and some of here doubts of being an idol. I can't say more because it will be some sopilers, so... let's continue. Ichigo is a person that anybody can admire. She knows that she can't do things alone, so, she accepts help of anyone so this is a good thing if you want to succeed, and she does in this movie.
If I am honest the music is good, while watching the movie, a lot of Aikatsu past songs return, so, if you like idol music you can sing with the characters. Basically the festival is only to show how many song Aikatsu has. The music is enjoyable, fun and invite you to dance with the characters. But personally if you hear too much those songs later you can get tired.
The problem with this movie is that it focused only on Ichigo and that's why I got mad with the movie at the first time I watch it. Why only Ichigo? Aikatsu have plenty of other Idols. Maybe a group festival... But thinking it, Ichigo is the first protagonist of the series, is her story, not the others (well, yes, but Ichigo is the important one). So, It is good that the movie protagonist is Ichigo. If you have this on mind you will enjoy the movie, just like me at the second round I watched it.
Overall is a 7. It is good, have an average animation, not too different of the main tv series, it doesn't have anything new things to anime. It is only a good opportunity to hear many Aikatsu songs all gathered. This and watch a conclusion on Ichigo and Mizuki idol activities, for now.
