I try to not watch 3D movies in general. The glasses are cumbersome and the movies are over priced.
A couple of months back, I was at a theatre looking to buy a ticket and was told the same movie only had 3D showings available at a particular time as the regular 2D was sold out. I thought it was just me ( I hate 3D because I already wear glasses ), but the cashier told me that a theatre, when selling tickets for a movie available in both 2D and 3D, will sell about 5 times more tickets to the 2D version.
