I'm not sure 3D glasses were needed through most of the movie. I took them off once and the color was much better without them! I was expecting a lot more, especially to see TRON, since that was the name of the movie. His role was basically non-existant. I agree with the person who said the motorcycle races were the highlight of the movie.
The movie was good for special effects. But it didn't need to be 2 1/2 hours long, as most people seem to agree. The movie subject is geared for kids...I know...I know adults go too!
My young grandchildren were with us. The vulgarity was unnecessary. The dog humping the leg; the dad smacking the mom's rear and taking her upstairs to bed. etc..etc. Kids are learning younger and younger now as it is. We don't need to help them along. If all those parts had been cut out it would have been a great show to take kids too.
