People should just leave this movie alone
I have nothing against any of the sequels or remakes of this movie, and people can enjoy whatever they want to enjoy - but in my mind, this is the perfect example of a movie that needs no sequel, prequel or even a remake. The more movies with this name that are made, the less impact the original movie has.
It would never have happened with the box office success this movie had, but they should have just left it at one. All these new movies trying to explain the origins of Leatherface are completely missing the point of what made the original so chilling.
Just my two cents!
