Finding Nemo 3D and Why 3D Filmmaking is not the Future

Three things I didn't know:
1. 3D releases are down this year from previous years.
2. 3D sales have dropped in recent years.
3. That Lion King 3D made massive money at the box office last fall.

Two opinions:
1. 3D sucks and is not worth it.
2. James Cameron hasn't made a good film since Terminator 2: Judgement Day.
(I don't know if these are opinions, or facts.)

One question:
What do people see in Avatar? The story was essentially Pocahontas in Space. I guess the effects were good. Whatever.
