I too don't like 3D and will always choose the 2D option when avaliable. If it wasn't avaliable then i'll just wait or the DVD, its not a problem.
This is the solution, if cinemas see ticket sales plummet for 3D films and remain constant for 2D they will quickly stop.
Iím not sure how much profit they actually make off tickets compared to the overpriced food. So even if 3D is more profitable then they may still lose money if less people are going to the cinema because they donít like 3D.
