I think the sales of 3D TVs are deceptive. Most new TVs and Blu-ray players are 3D whether the consumer wants it or not. I went ahead an bought a couple of pairs of active 3D glasses for my new 3D TV this year; but I'm not blown away by the technology. For the most part, 3D is just various 2D images which seem to be in 3D in relation to each other. the objects themselves still look 2D.
I admit I am looking forward to the Blu-ray releases announced for later this year from the golden age of 3D: Dial 'M' for Murder, House of Wax and Creature from the Black Lagoon.
When 3D movies first came out, I didn’t think too much of it either. When I went to see Avatar 3D I got sick during the scenes when the protagonist was trying to ride his bird.
But I find it enjoyable when a 3D action causes me to react as if something is coming at me.
In real life much of what you see looks 2D as well.
