Alright, I'm going to buck the trend.
Joyce hadn't seen any 3D on this TV yet (I had only seen a few minutes to see if it worked) so after dinner I put on the Lion Ling in 3D for her.... one of her long-time favorite movies.
Because my receiver is not 3D-compatible, we watched it with a direct connection between the B-D player and the TV...so we only had the TV sound.
Still, we both really enjoyed it! I don't know how it would fare with a non-animated movie, but it was just plain fun!
The 3D glasses were not troublesome or tiring, and worked fine over my normal glasses.
I'd have to say, if you poo-poo'd 3D in the past with active systems, you may want to try a passive system like my LG.
I don't know that I would necessarily use it often, but it was fun to have as an option in viewing!
Now I have to finish setting up the TV....when I have a chance!!
