Watching this movie again right now......I see a LOT of ghosting. Which is not too surprising since the movie is so dark, and it's high contrast scenes that lend themselves to ghosting.
I have a Panasonic VT20, and an obvious example of ghosting is the very first murder when the guy has the pick axe through the back of the head and the eye pops out. I can clearly see the ghosted image of his head to the left (his right, the lit side of his face).
Then as he falls, the light bulb behind him, it's set way back, so the two images for each eye are far apart, with the glasses on, you actually see three lights, the bright one in the middle and one on each side. Now it's only for a split second, but this kind of ghosting is present throughout the movie, and can be kind of distracting.
It's really noticeable if you pause the movie. I paused it at the moment he starts to fall, and it's very difficult for my eyes to even focus on the light behind him, i think because the ghosted images are so bright, it confuses my eyes.
On most of the animated movies I have, ghosting hasn't been too much of an issue, and most movies aren't this dark, so I'm not too worried about future movies.
