I love the video and completely agree that "Boyhood" should have won Best Picture. I'm completely baffled when people say, in regards to Linklater's movies such as "Boyhood" and the "Before" series, that nothing much happens. If ever there where movies where seemingly everything happens it's those movies. These movies are seemingly obsessed with how people change.
Linklater is such a sly filmmaker that it feels that people don't really take measure of his work in ways they would other movies. In the most simplest terms these movies are often described as being about time, or obsessed with time. But time is merely measurement in these stories, not what they are about.
One night in "Before Sunrise" changes two characters. Eighty minutes in "Before Sunset" changes these two characters completely. In "Boyhood" it's not the 12 years that changes the family but what they go through in those years. These films are really about context: what these characters covet, what they face, the things they reconsider, and how they change. These films show that time doesn't matter. Change can be slow; change can be fast. It all depends upon the context. And in the case of the "Before" series (which I call instead of a "trilogy" in case "Before Midnight" wasn't the end) you get two characters whose history only gets richer with each film because of their context.
To celebrate the 20th anniversary of "Before Sunrise" last month I made a mashup video of the "Before" series, playing with their contexts.
And "Dazed and Confused" was, yes, a "last day of school party" film but in a different context it's a movie about America's Bicentennial, showcasing teens in 1976 with focus on a high school quarterback debating about signing a sobriety pledge in order to play football--will he play into the system or will he go his own way, declaring his own independence?
Linklater's films run deeper than they can let on. He really loves to tell stories that approximate life, never hitting you over the head with what his agenda is but telling a stories that run deep enough for enormous discovery.
