I have a theory: What if in horror movies, they used real blood instead of fake blood? Would the real blood carry a certain spiritual vibe, that makes the movie scarier? Boyhood tests that theory. Filmed over 12 years, it upgrades Linklater's 'hyperrealism' experimentation from the Before Sunrise/Sunset/Midnight trilogy, and follows a boy/actor (with his family/other actors) from childhood to teenage years. The resulting coming-of-age story is profoundly ... real ; making it impossible to not sympathize with critical points of the boy's life. And like always, the best scenes are the ones with Ethan Hawke in them.
