I like to watch 2D movie more than 3D one. It lowers the excitement of mine when nice movies are released. Like , when Transformers 3 was released I was happy because it was shown in both 2D and 3D version in theaters but when Spiderman 4 was released I wasn't because it was released only in 3D. The 3d effect lowers the brightness of movie, and when it is a night scene, I hardly see anything. And as Skyslave said it hurt eyes too.
