Free write about project

I think our group has had a typical experience with this project. We've worked together in the typical fashion, we all find material to put in the book, and we all come up with ideas and suggestions. We all do pretty much the same amount of work. Our book is about a young boy and a monster that are learning how to share with one another.
My opinion on this project is that I don't really like it. Were in creative writing, and writing a book for kids. Children's books are simplistic with a simple theme. The only thing that really requires creativity is the illustrations. We aren't in creative art class.
