I haven't actually seen the film, and I will probably wait until it hits Netflix. But from what I have read, there were a lot of reshoots that the studio demanded to make the story more "modern". Originally it was supposed to be set in 1993, 20 years after the original movie is set (1973). But the studio decided they wanted to put in cell phones and iPhones and Skype and all that **** because the young audience would like that. Which is incredibly stupid. So they decided that the events of the original would now take place in 1992. Which of course is insulting to fans of the original and makes no sense at all. The original movie clearly says that it is set in 1973. I've read reviews of the film which state that there are shots of old newspapers in which the date "1973" is blocked out so you can't read it. So the girl is actually supposed to be 20, not 38. Even though changing the date makes no sense and the young audience doesn't care anyway, they just want to see Leatherface cut people up with his chainsaw. It's ridiculous.
This was all the studio's decision. The director and writers had no control over anything. It was originally announced as being "the true sequel to the original" (even though Chainsaw 2 kinda was that already) but somewhere along the way, all that changed thanks to studio interference. It was upon finding out about all this that I decided not to pay to see this film. To each their own.
