I generally hate it when "they" mess with things that have historical integrity, although I wouldn't mind too much seeing the obvious wires erased from a blu-ray of War of the Worlds. I think George Pal would have given that a thumbs-up. Now I'm feelin' guilty for sayin' it.
Naw, when the wires and such start poking out when they DIDN'T in the original, I'm all for fixing newly integrated flaws like that. I just don't like the idea of remaking history ala Lucas and Star Wars .
