As much as I disagree with people watching pirated or other material that was made in contravention of copyright legislation, I have to agree with 419 that simply watching the films/programs is in itself, not in any way illegal.
It's easy to state that it is illegal, but if this is indeed the case, why can't or won't anyone provide a link showing specific laws that are being broken?
"Just stop digging" doesn't mean anything without something to back it up.
It is illegal to manufacture or sell out such material, but simple ownership is not illegal so surely if so eone is convinced that the viewing of this is illegal, it shouldn't be hard for them to show what law is being broken.
