I took my 2 yr old and 4 yr old to see it in 3D on IMAX screen. Wasn't sure how 2yr old would react to 3D. 4 yr old LOVED every min. 2yr old got scared on previews of the new Dragon movie. 3D was a bit much for him. He peeked a few times, but the majority of the time had his eyes covered. I loved the movie and can't wait for DVD release. Not scary at all for the 4 yr old. The 2 yr old did comment the dragon (in the movie) was scary to him.
