From what I heard it was a complete puff piece before the news came out. No idea if they brought people back that they already interviewed (Bret Hart is someone who probably agreed to do more interviews), but they were forced to change the tone of the entire doc.
This is by Bill Simmons & Dave Shoemaker. Time will tell.
But, he was writing stuff like this back when Vince was all clear.

I'm seeing now, that he was on stage interviewing CM Punk and Fan Fest and does a wrestling podcast with Peter Rosenberg.
Right now, I'm sure WWE, itself ain't very pro-Vince McMahon. Which is weird to say.
