Adventures in Cultural Consumption:
Picnic at Hanging Rock: A movie where the tension, remarkably, just builds and builds. No answers, no resolution; only visually striking and well-paced and mysterious. Settles firmly the old debate about Lost: does a piece of entertainment built on mysteries need to resolve them to be satisfying? No. But it needs to be interesting.
(And, like Groundhog Day, there apparently is an explanation of what happened and why out there, but the author and director both had the good sense to omit it. No explanation is almost always better.
