I watched the 3D BluRay last week; the 3D was a mixed bag in my opinion with depth varying greatly from shot to shot (one would look as good as a native 3D image, the next completely flat). In terms of pop-out, I found the effect didn't work particularly well on my Samsung plasma - I've noticed that when watching letterboxed 3D movies on my TV the black bars tend to work against popout effects a lot of the time. Particle and smoke effects worked well enough but other stuff rarely seemed to break the plane of the screen. There was no ghosting to speak of, even on my older plasma, so that shouldn't be a factor on most panels.
