John Green's The Fault in Our Stars is one of the most popular young adult novels of the last several years, and one of the rare YA titles to make serious headway with adults as well. Through the lens of two love-struck teenagers—both of whom happen to have cancer—the novel addresses mortality and illness with clarity, humor, and depth. So it's understandable that in adapting Green's novel for the screen, director Josh Boone and screenwriters Scott Neustadter and Michael H. Weber hewed closely to it. In some regards, their respect for the novel pays off; other elements of the book probably should've stayed on the page. by Alison Hallett
