Boyhood is one of the 10 (really 11) best movies of 2014, according to the AFI.
If you haven’t seen it (or heard of it), Richard Linklater filmed it over the course of 12 years. It follows a family through remarriage and divorce and the effect that that (and life in general) has on the two kids. Because it was filmed over so long a period of time, the kids are played by the same people throughout. It’s especially lucky that the kids end up being decent actors (which is kind of a risk when you cast people at six or seven).
I really enjoyed this movie. It’s sad in parts, but it’s also incredibly well-made and poignant.
