FOX has been announcing for a couple of days that they are putting on a special - hosted by Jon Scott. Just from the clips I saw, it appears to be factual. I guess we'll find out.
Is the problem with BRAVO's Christmas Special one of factual error? You say that the FOX special will probably be "factual"... It's my understanding that people's problems with the BRAVO special have to do with the emphasis on behind-the-scenes unpleasantness and greed, but I haven't seen anything to suggest that these tawdry tales are inaccurate, just unnecessarily tawdry. Again, as someone else has already pointed out... what more do you really expect from televison?
