2010 was last year (Ok, it will be the year before last in a couple of days, but...), inflation is not sufficient to effect it that much when compared with this year.

Like the grand-parent, this does not fit with my experience. When I got to a new release I usually pay around $13 per person at a decent theater in Las Vegas, and up to $18 per person for Imax 3D.

But the other thing that may skew the results is budget or "dollar" theaters that show older releases. I frequently take my kids to those for around $2 per ticket.
