As someone who's studied wrestling history there was no new information for me.Watched Mr McMahon series on Netflix. A lot of it was covering ground that's already been covered in other documentaries (Raw v Nitro, Hulkamania, Montreal Screwjob). The family stuff was quite interesting but also very slim. Interesting for wrestling fans, not sure how much someone who isn't a fan (or has zero interest in pro wrestling) would enjoy.
Maybe someone who's a newer fan or hasn't watched any wrestling stuff it might be interesting for them
