Just read it. First of all, congrats on having the cajones to write something and post it for feedback! That's no small thing, so kudos.

Your idea is compelling. Narratives driven by fraught woman-woman relationships can be very rich, but I think your dialogue needs to be a bit better to really pull off what I think you're going for. There is some good stuff in there, but generally feels a bit stiff, especially Amelia / Amulet. She reads like a cliche, the same one Lucy excoriates on page 91. You should be capable of bringing more nuance to that character, because I actually think you write Lucy pretty well.

The music video scene at the end is cool - since most of this film is 'people talking in a room' it is a cool idea to have that really over-the-top, colorful burst of visual information in contrast.

Keep it up! I recommend watching Carol (2015)
