Draft of new paragraph edit: 
 "There are many differences between the original book and film, some of these include: 
 *The novel features an all-male Mobile Infantry and very little actual combat is shown, while the film focuses on heavy action scenes and the love triangle with Jonnie, Dizzy and Carmen. 
 *The novel is told exclusively from Jonnie's point of view describing his hero's journey from indifferent high school student (Appreciation of Television is listed on his transcript) to elite "cap trooper", and details the maturation process that entails. 
 *The film changes point-of-view focus between Jonnie and Carmen (who in the novel never had any relationship beyond friendship). 
 *The absence in the film of the "power armor" that was a central plot device in the novel, and had an entire chapter devoted to its description and use." 
 All of these differences are plain simply by looking at the primary sources, there is no judgement as to whether or not is is a "good" or "bad" change, and no POV judgement that these are the most important differences.  In a section titled "Comparison with the novel", there really does need to be more than just "there are many differences"
