3 D Movies

[Kinslayer]

Me and the GF sat down and started watching Journey to the Center of the Earth in 3D with the 3D glasses that came with them but we found it very hard to focus, kinda blurry and hard on the eyes. My Question is has anyone tried some of the better more expensive 3D glasses like the ones you get when you go to the Theatre?

I'd imagine there would be quite a bit if difference and it should be actually watchable with a good pair.
