DWA went public too early. JK wanted to raise a ton of money fast while relinquishing power so he went to the capital markets. DWA relies too heavily on the box office returns of just 2-3 properties a year, making it highly volatile in the eyes of shareholders and subject to intense pressure from said shareholders.
That "meta problem" aside, Hollywood lives in a bubble. 3D movie tickets are freaking expensive. A family of 4 is going to spend approximately $56 on tix plus another $25 on drinks/snacks. $80 is a hell of a lot of money to spend for 90 minutes of entertainment if you're an average American household (avg. per household income for family of four is about $50k). A great many families would much rather spend the same amount for a longer sports event, a nice dinner, or spend slightly more for a full day at an amusement park not named Disney.
