I pre-watch all new material, which means we don't watch a lot of movies. DS2.7 has watched the Toy Story trilogy, the original Winnie the Pooh movie (fast forwarding through the Heffalump scene), and The Incredibles.
(I have to put in a plug for The Incredibles, as its message of using your gifts to the fullest resonates well with a GT audience. This is DS' favourite movie--he loves the super hero baby, Jack Jack, and has glommed onto a line by the sarcastic fashion designer, Edna Mode. Highly recommend.)
A site I consult for some of our media is
www.commonsensemedia.org, and I reference the parent reviews. Generally, I try to identify potentially objectionable scenes from the comme ts and read the transcript for that section of the movie, as that can save me time watching material that will just be upsetting to DS.
This might be overkill for an older child, but it works for us now.
