i think art was done because he knew he was to ill to proceed.
If so, he could have been a national headline if he would down with grace. Maybe a series of goodbye shows with the great guests over the years. A humanization of his condition and the effects of smoking. He could have really gone out a hero, loved by all.
He could have slowly faded, rode off in the sunset and ramped up Heather.
Art fucked his legacy (pun?) massively and made it quite obvious that Ramona was the one
who's (😀) management made Art the name he was. She was his Brian Epstein - talent without discipline.
Heather will crash and burn. She is who she is. Her personality was set by age 7, add in hallucinogenic drugs, a world of grifting and probable onset of mental health issues (caused by drugs and naturally developed as she aged). I just hope she receives the first bullet out of her pistol instead of someone else... With her, I suspect that she'd target others first. Jus'sayin'...
