Why come no one is seeing the 2D screenings of today's 3D Movies? (i.e. Gravity & 47 Ronin)

[Cleary397]

Here in UK it costs around £3 - £4 more for a 3D movie, so i will rarely go and see a 3D film unless it is an animation or a film created with 3D specifically in mind, like Gravity.

If 2D and 3D screenings were the same price i would probably go for 3D just to see how the film utilised 3D

 

Edit: I also wear glasses for sight, so having to wear 2 pairs of glasses for 2+ hours isnt comfortable :/
