This movie is Sylvia Plath sad (spoilers)

Every little plot strand in the movie seems to end with unfulfillment.

Iris has no children, no spouse, no protege to take over her house like her estate plans require. Her most popular book has no ending.
Lily's lover is with someone else and she dies single, in her prime child-bearing years and spent her career always caring for people near death. She continued to fail to get a TV show for 11 months and couldn't even take an adventure of exploring Iris' trinkets drawers or read completely one of the novels.
Polly is murdered by her new husband on her honeymoon, still wearing white and maybe dying a virgin. She would never have true love; only betrayal.
All these women never knew the cry of their new born child and never grew old with a life partner; their ultimate fate is for their spirits to rot slowly in that house constantly reliving scattered sections of life just before death.

Even Lily's death was unfulfilling. She couldn't fight valiantly and lose the battle to a superior foe. Her screams just faded and she slowly sunk and expired hence forward into a rotting, fly infested heap. Not even to be found quickly by the plumber while her body was still a semblance of it's beautiful self.

The movie left me feeling like it was time to pick up a razor and slit my wrist.

That's the creepiness of this film. It oozes silent despair and unfulfilled lives.
