LOS ANGELES — The disasters were supposed to stay on the screen.

With extremely weak domestic ticket sales over the weekend for “R.I.P.D.” and “Turbo,” Hollywood has now sustained six big-budget duds since May 1, the start of the film industry’s high-stakes summer season. The other failing movies have been “After Earth,” “White House Down,” “Pacific Rim” and “The Lone Ranger.”

A couple of misfires, sure. But six?

Studios point to a number of problems, starting with that ever-pesky criterion, quality. In the Twitter age, audiences can spot a stinker from a mile away, and the unfortunately titled “R.I.P.D.” and “After Earth” in particular were both considered poorly made. But the deeper issue is an overreliance by studios on the same kind of expensive movie. One or more cinematic behemoths — those loaded with similar-looking computer-generated effects, films that cost $130 million to $225 million to make — have arrived almost weekly since May, fragmenting and fatiguing the audience.

Studios have also tried to sell most of these as “original,” which in Hollywood-speak means not a sequel or a remake. In reality, movie companies have largely just reassembled familiar parts. “Pacific Rim,” which featured giant robots, seemed to share DNA with “Transformers.” “The Lone Ranger” was “Pirates of the Caribbean” in Old West drag. “R.I.P.D.” was “Men in Black” lite.

Moviegoers are pushing back. The No. 1 movie in North America over the weekend was “The Conjuring,” a period haunted house film that cost Warner Brothers $20 million to make and received stellar reviews. It took in $41.5 million, according to box office estimates compiled by Hollywood.com.
