What you need to do is play up the parts of the story that are going to be appealing to the audience that you are trying to reach. In addition to what the first post said, I think that you should play up ideas of loyalty and heroism, of being willing to die for your friends and for good causes. You should play up the idea of romance and of being attracted to the wrong people (Cherry is attracted to guys like that).
I think that you should make sure to make your review sound relatively casual. You don't want to make it sound like it is an academic work. So use informal language if your teacher will let you.
Looking at one of the three themes, or even all three of the themes mentioned in the links below would be a great start for your paper. Additionally, you could discuss how rebellion impacts a young person's life. There are so many struggles in the story that the characters deal with and how they go about trying to find a place for themselves in the world. Rebellion is always a popular element for any young person and that is the intended audience for the story. Finally, this is one story that I certainly think the film version does justice to the book. Taken from that angle, you should be able to write a very convincing argument!
