This is what Simcha thinks after his Talpiot documentary:

1. By the way, I’ve got to tell you that I think this story you know I mean you could shut up Galileo, you could shut up Copernicus, you could argue that the earth was flat for a while and you think you won a victory on the day you shut up Galileo, but at the end of the day the earth is round and its not at the center of our universe.  So at the end of the day, truth has a funny way of coming out.
   

Further, his film was aired only once because of over a million emails:

1. All of this was upsetting so what happened was a tremendous amount of, I mean there’s a lot of internet chatter, there’s been I think six books against my book.  Dr. Charlie Pellegrino and I, we wrote the book and I think there have been six books and three films already arguing against our presentation that this might very well be the tomb of Jesus.  There’s so much pressure brought to bear on Discovery that they aired it once and even though it was their highest rated show of the year, actually more than a year, they never aired it again.  They pulled all subsequent airings.  Because there were over a million emails I think threatening sponsors and so on.
   

I thought it wasn’t aired again because the authors’ conjectures were debunked one after the other. But I may be wrong...
