4. The Time Of Day
This one might sound a bit weird but the time of the day does play a big role in whether or not the 3D will work on the movie. No, this does not have anything to do with your mood or with the alienation of the stars but actually this one is really tied up to the current technology used for 3D movies. You've probably noticed by now that when you're watching a 3D movie in a theater they give this big glasses that have nothing in common with the traditional cellophane glasses. The reason behind this is a bit complicated, but basically what they do is that one image would be projected from a certain angle and the other one from a different one, the glasses then would take those images and arrange them to create the illusion of depth.

Well, this new 3D glasses require batteries in order to work, and while some theaters take the time to charge those batteries again most of them do it once the day is over. And as usual with anything that uses batteries, the less energy it has the less it will work. Sure, there are some exceptions (with midnight screenings they use charged glasses) but if you're going to watch a 3D movie at 6pm it's quite likely that the glasses won't work properly.
