I was so excited to go see Harry Potter in 3D. I waited to see it untill this weekend to experience the IMAX 3D. What a scam! The first 10 minutes of the movie is 3D, then NOTHING!! I kept waiting for the little gasses to reappear on the screen to put the 3D glasses back on, and they never did. VERY DISSAPPOINTING!!! The movie itself was just ok, so it didn't make up for the one scene we got in 3D. If you advertise a movie as 3D, I think it should be the WHOLE movie. Very upsetting.
