We went to the theater to see the 7:50 show in 3D, and the woman at the ticket counter says, sorry, that's actually in 2D. But there was a show that was starting in 2 minutes in 3D. She surprisingly did not charge us the extra $$ to go to that show. So we saw it in 3D (yes, me, the man who hates 3D, saw a film in 3D)...
And to be honest, I thought the 3D did absolutely nothing for the film. I almost felt gyped, in that the characters did not feel as real to me as they did in the earlier films. I look forward to the BD in 2D. Loved the film, a great end to the series that paid great homage to the earlier stories.
But I was pleased that the 3D did not give me a headache or anything. The technology has definitely improved, but I still am not a fan of the genre for LONG films.
