I took my 2 yo. to see this movie last night and he loved it. He kept the 3D glasses on the whole time, he was interacting with the screen, telling the Dragons to "stop" when they were fighting. The 3D effects were amazing, the scene with the ash floating threw the air was great. There was adult humor but not raunchy or tasteless, more like sarcasim. We are going to see this again!
