If a 3D movie is done right, it will make it look more real, not gimicky. It should not have hatches leaving the screen right to your head or dinasaur spit flinging in your face. That said, it needs to be clean and not cause any discomfort. The glasses from Disney are comfortable and I forget I'm wearing them.

If the movie was made to be seen in 3D, you are not seeing it the way the film maker intended if you don't see it in 3D. Therefore you are not doing it or them justice.
