I watched the Substance but I got questions ...

I watched The Substance over the weekend, and all I can say is WOW—Demi Moore absolutely crushed it! Her performance was incredible, hands down. But honestly, this movie messed with my head big time. It was such a trip watching someone literally battle themselves for a better life and ambitions. Like...how do you even process that?

But now I’ve got questions. So, was Elizabeth actually living Sue’s life while she was asleep, or were they completely separate lives? Because if it’s the second one, then what’s even the point of having a double? Especially one who doesn’t look like you, doesn’t have your name, and basically steals your life while you’re stuck living a nightmare. Like, what?? But if Elizabeth was experiencing it all herself, then why did she make those terrible choices? Was she sabotaging herself on purpose? I loved the movie, but this part has me spiraling a bit.

Did anyone else feel the same way or catch something I missed?
