To me, 3D is just hype and another fad racing towards it's own demise...again.
It happens in Hollywood where they make an advance in 3D, put out a couple years of movies and then sales start to slump and the novelty wears off.
It's a little more profound this time around as technology is keeping it alive somewhat, but I don't see it lasting.
I have seen Thor in 3D and it was good, and I really didn't have eye strain leaving the theater. Saw Transformers 3 in IMAX 3D and my eyes felt like they would explode when I got out of the theater. The technologies between the 2 different types of 3D was fairly large. One used slightly colored glasses (and gave my the horrible eye strain) and the other was based on opposite polarization of the lenses (one vertical and one horizontal) Which felt fine.
When it comes to home theater or even a phone, this new 3D tech is still too new to be "safe" and enjoyable.
Some will scream it's the future and demand it now. Others have seen the cycle, and know it's going to die off in a bit and the next resurrection should be decent. Plus to the others, it's not a big deal.
