I'm going to get the elephant in the room out of the way first-- I'm not religious. As such, I'm not usually a fan of the exorcism/demon possession genre, since it tends to rely on Christian plot devices that I'm not overly familiar with. So when I say that I enjoyed this script, I really mean it. The main character and his motives were interesting, and the way the world was set up fascinated me in a way that most other stories in this genre rarely do. The structure itself didn't have any significant issues I noticed, and the dialogue was slick, snappy, and altogether more "modern" than I expected from this kind of story. I say that as a compliment, by the way; so many other movies like this I've watched seem to be stuck in the past and feel like a chore to watch. If this ever gets made into a movie, I'd love to watch it.
A decent concept, and one I'd love to see made into an actual movie, but not without a lot of problems. It feels like a lot of the time it's reveling in its own darkness and violence, bombarding the audience with characters who seem un-relatable outside of being violent and foul-mouthed. "Edgy", I believe, is the word. There's definitely a good story hidden underneath all that excess, and one that could shine through with a little extra work, and I'm interested to see what the final product looks like.
Two kids from Earth befriend a shapeshifting girl from another dimension, and discover an evil plot that threatens to destroy the multiverse.
