Like, for example, it uses things that were made up and imagined in those horror movies, and then uses them for Ed Gein...so what is going on here? What is the dialogue we're supposed to be having at the horror movies and horror filmmakers? Is Ian Brennan saying that Alfred Hitchcock and Tobe Hooper are the real monsters?
Yes, the characters and events of those movies were loosely inspired by Ed Gein and his murders, but they were fantasy for the most part, make-believe. They were not real-life people or figures.
Meanwhile, based on a true story Ed Gein show presents Ed Gein being involved with murders that he literally had nothing to do with or was never connected to.
I mean, yes, with movies and TV shows based on true people and real events, you expect falsehoods and creative license, but not to this level of brain rot.
IMHO, Netflix, critics, and audiences rewarded Ryan Murphy and Ian Brennan far too much and gave them huge egos, making them far too comfortable to do whatever they wanted and get away with everything.
