(Average) The Substance

Movie in one sentence:
Dr. Jekyll and Ms. Hide.

Movie in more sentences:
A once famous movie star sees her fame fading, and when she gets fired from her job as a TV workout instructor for being too old, decides to call the curious phone number given to her by a young man.

A mysterious package is left behind, with drugs and tools that promise rejuvenation, but not by any conventional means. A new girl is born from Elisabeth's body, claimed to be her, yet someone she can't control. The younger Sue keeps eating away at her, causing her to grow ugly and even older, yet she's unable to quit the drug.

..How did Elisabeth know what needed to be done? The package came with instructions, but they were so minimalistic, I would've never understood.

Anyway, this movie ended up being soft porn, very unfortunate. If the times a woman's crotch was shoved in my face was spent on exploring the inner struggles of the main character(s), this would've been a decent commentary video. I think that's what it wanted to be, but then there's the comically weird ending, and I'm left wondering.

It's also a bit confusing how these two women share one life. At first, it seems like they have each other's memories. They know where to find their house, workplace, and how "the substance" works after all, but then you have these moments where Elisabeth watches a TV interview starring Sue with curiosity about what she'll say, while Sue keeps waking up to trash lying around the house -evidentially not knowing she herself did this. So, then, they are not each other..?

Perhaps Sue only knows what Elisabeth knew at the point she first emerged, whereafter their minds became disconnected? The movie doesn't explain.

Wasted potential.
