If Superman is going to have a 3D release, I hope for two things;
1) That it is filmed in 3D and not converted during post
2) A 2D version is available at the cinemas so that we have a choice of how to view
That way there is no problem, and we all get what we want.
BTW, I love (real) 3D movies.
Recently bought a 42" 3D Panasonic plasma TV and 3D Blu-Ray player and was blown away with the 3D quality on my Avatar 3D Blu-Ray disc.
But people should always have the choice at the cinema as it is not for everybody. Whether it is because of a choice or physical issue, makes no difference, you should not have to pay extra to either get a splitting headache or not see the effect.
