Like how Baby Jane is written as this repellantly grotesque creature of addiction, depression and insanity -- the sort you don't even need your mother to warn you about. And yet Davis took this horrifying character and did the unthinkable, she made her likeable and sympathetic. She seemed to understand that this miserable soul was victimised by her demanding stage dad and her insidiously deceitful sister over many decades, which provoked her to commit outrageous acts to terrorise Blanche into a state of perpetual fear. But her characterisation and delivery made you side with her all the way. She's not really the antagonist as her Wiki entry states, but more of an anti-heroine.
Rather like how Perkins made this pitiful and emasculated character Norman Bates so interestingly nuanced through his quirkiness, his cloak of innocence and his mild mannered demeanour. Something Gus Van Sant and Vince Vaughn missed completely in their bizarre wank of a remake. Vaughn's Norman was a creep from the moment you meet him.
That said, I retract my statement calling for a Baby Jane TV series. They'd just fuck it up as badly as that shitty Lynn Redgrave tele flick.
