The 3D movie Fad... What's the point?

FYI: If you look at that image with 3d glasses... the Leopard drools on your face.

I've always said, and I'll quote myself, that "in 15, 20 years, people will not be able to watch 2 dimensional movies."  Whether i believe that statement anymore, i don't even know. 

There's always a bit more excitement coming into a movie that is 3d. Recently Pixar Animation studios released a statement sayings that all of their future movie releases will be in 3d. There are some movies that simply are meant for 3d. Kids movies being one and the random action movie that has a ton of flying obstacles being another.  Recently TV networks have started broadcasting Television shows in 3D. NBC's Chuck was broadcasted the day after the Superbowl, and many fans sat in front of their screens with the classic goggles attached to their faces. But the real question is does the 3D experience really heighten your enjoyment at a movie theatre, or watching your favorite show? Since I'm taking economics in University, and all i see all day are formulas, I'm going to create one myself to see if 3D is worth it for me, focusing more on the movies in theatre. 

Main Rule: I'm going to add different variables. The variables will be anywhere from -10 to +10, if the final number is above 0, 3D is a worthwhile investment for the movie industry because this formula says so.

Variable 1 (-2):   Extra cost of 3D glasses at theatres ($3)

Variable 2 (-2):  Nauseous feeling after leaving the theatre.

Variable 3 (+6): Improvement of Visual effects.

Variable 4 (-3):  Annoyance of wearing goggles.

Variable 5 (+2): Does it improve the average movie experience

V1+V2+V3+V4+V5 = Legitimacy of 3D movies.

-2 + (-2) + 6 + (-3) + 2= +1

As i expected, there would be no standout decision. There are positives and there are negatives with regard to 3D movies. The only reason that the film industry should lean towards 3D is because it symbolizes change in something that hasn't really changed since color was introduced to the big screen. 

Were still waiting for that 3D movie that's going to blow us all away, (Hopefully James Cameron's Avatar), but until that happens, my +1 will remain the same.
