I read the book, found it boring, but enjoyed all the 80s pop culture references. Movie focuses on the main characters of the story, tries to cut down on all the pop culture references, and focuses on having pretty cgi. Only problem with all that is the only thing unique about the novel was the pop culture references and total worship of everything 80s. Without that geekiness front and center this film is a soulless, childish and totally forgettable flick that honestly has nothing to offer. Or to put it another way, it's pretty damn boring to watch.
