3. The Theatre Where You See The Movie
This one's pretty tied up to what I said earlier about the 3D glasses. A good theater will take the time to recharge the batteries of the 3D glasses no matter what time of the day it is. But it's not just about that, the installations and equipment that a theater has will vary from theater to theater (even in theaters from the same corporation) so the difference between them will be noticeable right from the start. You can't go to the Dollar Theater and expect them to have the best installations in the world, so even if a movie is filmed in 3D with thousands of dollars invested just to make it look right if you go and see it in a bad theater is still going to look like crap. This does not mean that a good theater will make a crappy 3D movie looks better, but it won't make a good 3D movie look like a pop-up book.
