Nothing could have prepared me for this film. That's not to say it was totally out there, more that the premise didn't quite lend itself to what we finally got. An almost unrecognisable (to me, but still great) Demi Moore stars as the insecure star desperate to cling on to her perceived value.
The film is zany, maybe even a little gonzo and very graphic - at times uncomfortably so. It even threw back to some 80s classics at times (I'm looking at you, The Fly).
One criticism is that it might have laboured its point a bit too much, and as such felt overly long at times. Other than that, The Substance is a curious movie that's worth the time it asks for.
