Wow, way to get defensive by only paying attention to part of my post. I was talking about all the silly fear mongering scaring people (like you and your wife), who very likely would have really enjoyed the 48fps, from going to see it that way.
It is a little different, but it isn't going to make your head explode, cause brain damage, or permanent harm, or even really ruin the experience of the movie if you don't let it (by skyjeding the hell out of it and freaking out about how it is going to destroy cinema, your childhood, and your life all in one blow). I can imagine if there had been an all black and white release of The Wizard of Oz, people may have opted to go see that for fear of color ruining the film for them.
At least my silly opinion isn't based on whiny people freaking out over scary change.
