You can't see 3D movie without wearing 3D glasses. If you do not have 3D glasses on during the movie, you will not enjoy the fun of watching 3D movie. To achieve the 3D effect, some movies use a dual-color technique while the others use a dual-polarization effect. Taking off the 3D glasses, you will see the movie as 2D with blurriness of the images or outlined in blue and red. I suggest that you should buy a pair of 3D glasses or receive the glasses handed out by the cinema, or you'll have a really bad time in the cinema.
