3D Cinema at the Slide?

After "Avatar" people assumed that 3D would take over as 80% of the people who when to see it saw it in 3D. The intake for 3D has gone down since Avatar which suggests that moviegoers are unwillling to pay more for uneven quality. For example, only 45% of the opening box-office revenue for "Despicable Me" came from 3D distribution.

Studio executives are sure that the public are not losing interest in 3D despite data showing a dropping percentage of thev amount of the box-office sales on 3D tickets. They think the reason for this is that childrens' 3D films are less popular because it's had to get the kids to keep the glasses on, so parents don't take them to see 3D films however films that pull in more adults like Alice in Wonderland and Avatar do better.
