Yes, when the children were first invited, I’m sure they were thrilled. But I doubt they were thrilled by the end of their visit if anything happened.
I actually watched the documentary. The kids were enthralled by the star power and magnetism of the king of pop, and the kinds of access it provided them. He built a theme park and zoo of his own for the kids to romp around, play games, rides etc. It was an elaborate trap. He convinced the parents that it was all innocent, that he loved seeing kids play because he himself had no childhood since he worked as an entertainer from a very young age. He lavished them with attention, gifts, trips, extended stays at his theme park etc. He indulged their other desires, financing their films or teaching them choreography, paying off their mortgages. He ran such game on the kids minds that many of them protected the secret and even testified on his behalf when they knew the truth was different.
Nothing was ever going to stop this freak from getting what he wanted. He built that ranch to snag kids. He would have gotten to kids someway. Those perverts always do.
