Japanese millennials aren't interested in cars, sex or marriage according to economists and business magazines such as Toyo Keizai. Yawn — so, what else is new? Every night I go to sleep hoping to wake up to a world where people go on proper dates and then grow old together and hold hands in cafes instead of taking Instagram photos of avocado on toast. But in the morning, it's always the same. The same old world where SNS has taken over and it rules the innermost recesses of our collective consciousness. Bummer.

Today's lifestyle, however, does also spawn movies like "Nerve," which is a running commentary about how social networking sites and services have invaded every facet of modern society, especially for millennials who can't seem to fathom life without apps. Not that "Nerve" demands that everyone should mend their ways. Nor does it inspire hordes of people to keep their phones out of sight in brunch establishments.

In fact, "Nerve" pretty much squanders the opportunity to convey any messages that are constructive or memorable — the movie is jittery and restless with no idea where it's going. Eventually, it runs out of stamina and flops to the floor. That, of course, could be the point of this whole endeavor — and the ultimate statement about our modern, app-addicted society.
