3D is the most pointless tech for the home market. I sort of kind of but not really get why it might be ok for the cinema but even then I prefer a plain old 2D. The worst showcase of this was watching the Hobbit in a local Vue in 3D AND in HFR. It was like watching a soap opera, sped up .... in 3D. It was nothing short of awful.
My inlaws have an x years old 46" Samsung with "smooth motion" feature/bug enabled. Again, just like the HFR malarkey in the cinema, it was unwatchable on movies and no different watching anything else. I turned it off and no-one noticed. People who don't notice it don't care about it and those who do notice it, hate it.
HD is just about enough for me. A good quality source is perfect for home viewing. Especially on a 37" TV... and there's no room in the corner for anything larger...
