The Family: Old man/Leatherface/Grandpa/ Chop Top

The Issues: Um...well...actually, if this list is taken to be one of dysfunctional families in the strictest sense, then the murderous inbred cannibal stars of Tobe Hooper's horror opus probably shouldn't be here - they're not exactly The Joneses, but they do sort of function as a unit, up to a point.

And it was either them or their distant relatives the Firefly family.

Mind you, that wouldn't get them very far in court, we fear. "Yes m'lud, my client realises that power-tooling people's faces off is generally viewed as unacceptable, but asks that the jury acknowledge his reasonably stable relationship with his mute brother, who he only occasionally beats with sticks at moments of high slaughter-induced excitement."

Would Therapy Help? Again, you'd have to be going some to find a therapist willing to take this case on.

Possibly some desperate work experience kid might agree to it, but even so, they'd be unlikely to get very far - we're not sure how much insight could be gleaned from Leatherface's whinnies, giggles, shrieks and grunts, even if he genuinely was attempting to open up about his mother. Who he probably ate.
