Is A Machine For Pigs best suited to a 'mature' audience?

[MyRedNeptune]

"Yeah, it had mutilated Frankensteined pigmen zombies working as slave labour in a giant secret underground machine by a man haunted by his own conscience for what he's done to his family and the people in his community as he pieces his memory back together after visiting sacrificial temples in Mexico...".

I bolded the parts that are cliche. Maybe that'll help shed some light on why I considered it uninteresting.

Note that the only unbolded parts are those related to setting/background/theme.
