When done right, like in Avatar and Tron: Legacy, the 3D-effect can be nice, but usually it looks as if someone just added a few layers during post-production and gave them a pseudo-dimensionality for the fun of it.

It's not exactly magical and doesn't really add much to most films I saw with the feature.

Adoption at home is probably underwhelming for the people pushing the Blu-Ray Disc 3D standard.
