Seen any good movies lately? Seen any movies? Chances are you have — but maybe not in an actual theater. Americans used to adore going out to the movies, but that love has been on the rocks for decades. Once, the rival was television. Maybe it still is given that so much more of what’s produced specifically for the small screen seems so much more worthwhile (or at least watchable) than it once did. But the threat to movies appears more existential now, because the very digital revolution that has changed how movies are made has also changed how many of us watch them.

Movies are no longer only in theaters or living rooms, but also on our devices, streaming at us wherever and whenever we want them — that is, if the connection is good and you have access both to the Internet and to devices. (Less than half of lower-income households in the United States have Internet service at home.) But like every other digital advance, the on-demand era brings loss and anxiety in its wake, including whether movies — one of the defining mass arts of the 20th century — can continue to provide a communal experience. The chief film critics for The Times, Manohla Dargis and A. O. Scott, consider the state of moviegoing in an era of omnipresent screens.

MANOHLA DARGIS One of the big, possibly bad movie stories of the last few months has been Sean Parker and Prem Akkaraju’s proposed new venture, Screening Room, which would bring first-run movies into living rooms for $50 a pop for 48 hours, though customers would also have to pony up $150 for the device to stream these titles. A lot of the news stories on Screening Room have focused on the industry: Theater owners have given it the thumbs down, because it will cut into their business, as have those lovers of big-screen spectacle, Christopher Nolan and James Cameron. Those who support it include Steven Spielberg and, surprisingly, Martin Scorsese.
