Everyone should know the Von Erich history so they hate the movie bc it's not historically accurate instead of actually having a good time...duh
Not saying that's what Sabs might say but I will say the people who think like this have such a reductive view of the Von Erich family. Unless you're super into wrestling history or grew up in Dallas around the 70s and 80s, I don't think many people actually know about the Von Erichs, or probably tangentially know about it.
When compared to stuff like Owen Hart, Eddie Guerrero, Chris Benoit, etc. The Von Erich family is pretty fucking sad, but I think ultimately overlooked even by wrestling historians. Chances are David would have won the NWA title but no one can say for certain if he was gonna be a big star in wrestling or JCP/WCW. He might have had a chance in WWF tho.
