I did check out the passive 3D this past weekend. I used Verizon FIOS On Demand, HBO, Green Lantern. WOW was I pleasantly surprised.
A bright detailed punchy picture with incredible depth and no ghosting whatsoever. Also, I did not see any evidence of loss of resolution that seemed to plague the passive 3D LG TVs last year. The passive glasses are very light and easy to get used to.
I may be watching more 3D after all!!!
