Reed's award-winning 'Leaving Neverland' focused on the stories of Robson and Safechuck, and their accusations against the pop icon.
But Reed was shocked by the reaction to the documentary, which prompted Jackson fans to come to the defence of the deceased star, raising money to create their own counter-documentary.
He told the Guardian newspaper: "As soon as the movie was announced, people were denouncing the victims without even knowing who they were. It was just a knee-jerk reaction: these guys are liars.
"And you can't challenge them with facts because it's an article of faith for them and any challenges to that belief are blasphemy."
Despite making the documentary, Reed doesn't want people to stop listening to Jackson's hits.
Instead, he urges music fans to simply listen to the allegations.
He explained: "I'm not about cancelling Jackson. But I think people should know that he was, at times, a monster to children."
