Well, there's actually a couple of good ones. BB01 had the "Casting Special" before the show premiered, BB02 had the "Who Will They Be?" special and BB03 had quite a few documentary episodes overall, including "Would You? Could You? Should You?" after the season.I need to get my hands on these documentaries, did you youtube them?
The good ol' days will be just that. I will never get the satisfaction of saying that about the new bb format
