3D Movies at the Henn

I need to know how important 3D is to my customers.  I am considering taking the Henn Theatre to 3D, but it's a BIG expense and I want to know just how important 3D is to you.  Leave me a comment and let me know a few things.
1) If you currently attend the Henn, would you come more often if it had 3D?
2) If you don't come to the Henn right now, would you come if it had 3D?
3) If you don't go to the Henn and instead drive to Fieldstone, would you instead come to the Henn if it had 3D for the same movie as the Fieldstone?

Thank you for any information you can offer!
