I would normally go to the Odeon on Orange Wednesdays and so pay 6.80 for 2 of us. If we go to IMAX it will be 18 pound cos they don't do Orange Wednesday and it's already a couple of pound more expensive than the Odeon anyway. It's not in 3D or anything, so is it worth it or not? I've never been to IMAX before ... can you tell much difference between watching a 2D film there and a 2D film at any other cinema?
