LIFE DOESN'T GIVE YOU BUMPERS: Good god, yes, you need to see Richard Linklater's Boyhood, a magical, audacious, humanist masterpiece unlike anything I've ever seen.
You know the basics by now, probably: it was filmed over a twelve-year period, starting before Linklater shot School of Rock, and we see a child become a young man while understanding so many of the things which affect his (and his family's) journey: being a child of (and parent in) divorce, the importance of work and discipline, the power of language and culture in shaping our lives, economic insecurity, Texas, everything.
It is powerful stuff; the acting (esp. Patricia Arquette and Ellar Coltrane) is spot-on; the emotional moments (large and small) are well-earned. It's a special movie. See it.
