I'm pretty sure part of the problem is tied to the different Netflix apps for different 3D devices. I own two 3D TVs - a 2010 Samsung and a 2012 LG; each has a PS3 connected to it via high speed HDMI cable. Each TV is also networked and has its own Netflix app.
None of the Scary Tales shows worked on either TV thru their respective PS3's Netflix app, exhibiting horribly bad flicker and skipping, as if the left and right images were not in sync. But when I watched them thru the LG TV's Netflix app, they all worked just fine.
I think Netflix needs some feedback from viewers informing them that they need to take another look at their 3D implementation across all their supported devices. They also need to do a better job of listing which of their movies are available in 3D.
