Now that I have my nice 55" PASSIVE 3D TV I finally have a boatload of glasses and can share 3D content more easily with a group. Right now I have MANY of the more recent 3D kids movies (Hotel Transylvania, Rio, Tangled, Hugo, etc.) along with Avatar, Avengers, Captain America. I thought of maybe picking up one of those IMAX or whatever 3D experience discs. Hubble or Under the Sea or whatever. Which one(s) to get?
