Last week a media analyst blamed theaters for the price hikes that boost some 3-D movie tickets just shy of $20, but they protest it’s not their fault. An AMC spokesman said moviegoers should blame James Cameron, and other deep-pocketed purveyors of new technology. "It is inevitable some of those costs will eventually appear at the box office," he said. Another expert used the “come on, it’s not that bad,” justification: "In New York, especially Manhattan, $20 for a couple of hours entertainment is relatively inexpensive," an NPD Group rep told the News. Be that as it may some cinema enthusiasts threatened they might not stand for it. "I probably wouldn't spend that much," said one, "The way the economy is right now, it's far too expensive."
