Haven't seen it, so I can't comment.
On the idea of an HBO Max show...I kind of like that. My only concern...well, one of them...is that they'd be tempted to make her dark, have her kill, have her whine and cry, or otherwise change her character because they want to be edgy. Or their definition of edgy.
But long form storytelling done right allows for a lot more thorough exploration of character than a movie, and of course just give a lot more time to watch the character, so there's a lot to like.
