Look at the decrease in time between each 3D movie's release. This graph could just be showing that we now have more 3D movies competing for the same number of 3D screens.
If we wanted to determine if 3D film was really 'dying', we should be looking at total revenue earned by all 3D movies over time, and see whether or not that is increasing or decreasing.
