I didn't have white lines, but parts of it were so dark it almost looked like I was watching and b&w movie.
Everyone's comments were absolutely dead on for me. I have a feeling that I would have loved this Lear if I saw it live or if they'd taped an actual performance, but what I saw last night was sapped of all energy and terribly shot. Parts of it seemed disjointed thanks to the hideous cut aways and sudden close ups. I was so upset.
As to the nudity, there was nothing from the front, and only a little of the back.
