I was just informed that Disney is releasing The Lion King in 3D in movie theaters. (While I hear that The Nightmare Before Christmas in 3D is awesome, I'm sick of 3D.) The last Harry Potter (July 15) will be in 3D, and I will have to double check all movies for the rest of my life, and make sure I'm seeing the 2D version.
The first 3D craze of the 80's wasn't nearly so obnoxious and long-lived. I blame Avatar. Stupid, Avatar.
