However, the film's biggest flaw to me-- as a person who's read the novel-- is that it barely scrapes the surface of what the characters and their development, and their relationships were. For instance, Russell and Kevin's relationship, whilst sweetly and endearingly portrayed in the film, was simply not explored nearly enough to be able to understand the depth of his feelings for Kevin (and vice versa). In the book, (SPOILERS) the reason why Kevin and Russell's break up at the end is so heartbreaking is because they were still in love with each other afterwards, they both wanted different things as characters--Russell was prepared to be out whilst Kevin was not--and they knew that it couldn't work despite their feelings for each other. In the film, it's just not very satisfyingly portrayed. The characters aren't as layered as they are in the book.
What I'm trying to say is that there is so much more to these characters than what you see in the film--which really only barely scrapes the surface of them. Their motivations behind their decisions and their priorities-- what is important to them and what (and who) they care about is what makes them and their stories so compelling. I understand that liberties have to be taken when adapting content to the screen, and while the way the characters are seen very much fit the narrative direction the film chose, I just didn't feel as if we spent enough time with them to truly understand their relationships--their growth or deterioration, and feel what they're going through. What's simply missing here is a sense of narrative resolution.
This being said however, Geography Club is a must see film for adolescents. I can almost guarantee that there will be something or someone in the film that any viewer will be able to identify with and or relate to. It's fast, it's funny, it's inspiring and it's flawed, but I cannot recommend it more. It's such an important film that I am sure viewers from all walks of life will recognize its importance.
