Once upon a time, Joss Whedon was a nerd king, the man behind Buffy, Angel, Firefly, Marvel’s The Avengers and more, known for his witty wordplay and dramatic, emotional scripts. More recently, he’s been in personal hot water over accusations of bad behaviour and inauthenticity, while there are ongoing allegations from his time overseeing the Justice League re-shoots. The Nevers, the new show he was making for US cable channel HBO, represented a chance to garner some better professional press, but now he has left the series.
