Horrible Continuity.
This film has so many issues but I only want to mention the horrible continuity with the first, oringinal TCM. First, who the hell were those Duck Dynasty lookalikes who were members of Leatherface's family at the beginning? I thought their inclusion was bogus and somewhat normalized the most terrifying and twisted family in horror films. I guess the inclusion of a female family member was intregal to the plot though.
A more severe gripe of mine is the age of the lead female protagonist. She was supposed to have been born in 1973 but she looks no older than 25 in 2013! What the fuck...all because they wanted to show off a hot young actress? If it was really necessary not to make it interesting by having an older female lead in a horror film, they could have set the film in the 90's - which wouldn't have been too bad either.
Notice too that thanks to the judgement of having a young actress, they could never reveal that the oringinal events took place in 1973. That none of the tombstones could even have dates on them - a possible first in cinema history.
