It starts as a fascinating character study of John and the corrupt backwoods town he lives in, but pretty quickly you realize it's much more about John than his town
Then the dude offs himself in a horrifying fashion and it morphs into political tug of war/treasure hunt/legal drama that never really gets resolved in any meaningful way (they do shoehorn in some 11th hour allusions about the "treasure hunt", though)
Along the way everything you thought you knew about Tyler and the cousins sort of gets upended and there's not much in the way of closure on either side of the equation
And then all of a sudden by the end we're finding out that John was really just a mentally ill genius, possibly mercury poisoned(!), masochistic, partially closeted homosexual longing for human connection, and that his town really isn't all that shitty or corrupt after all
I enjoyed it, but it definitely meandered unexpectedly, and not always in a good way.
"The night he killed himself, I pierced his nipples..." Um, ohhhkay?
you sure do seem to have a lot of time on your hands to be on this forum? Do you have a job? Are you a shut-in?
