I tried a 3D TV in a high street retailer (which admittedly might not have been well set up) playing Mosters vs Aliens, which seems to be the de-facto demo and giveaway. To me, it looked like the magazines I used to buy as a kid with 3D glasses; more like various planes if 2D images than a 3D image, like decoupage almost.
Certainly not something I'm interested in if this is as good as it gets at the moment.
Buy a good quality normal set IMO.
This. tried to watch a Samsung demo in a store the other day. The glasses batteries had gone flat. Not impressed TBH. It's a fad that will come & go & I for one will not be buying into it.
