You're doing it wrong. Just kidding. There are some things that come flying out of the screen so quickly your eyes can't resolve it. However, I had some friends over and watched a movie. At the quick popout scenes they were wowed, but I felt underwhelmed as I experienced the same thing you mentioned. I have an astigmatism in my eyes and I'm wondering if that could be it. As far as the rest of the 3D is concerned, though, I see it just fine (depth and popout scenes that don't come flying out at me). Check out Imax: Under the Sea. I find a fair bit of the 3D difficult to resolve, but when you get to the potato cod scene that sucker comes right out of the screen crystal clear.
