ASCENSION frames mental illness as a dark and sinister force from the stars. It makes the behavior understandable on some level. The person you know and love isn’t doing these terrible things. It’s that dark entity. That thing.
What’s surprising is that even with some of the usual modern rom-com conventions we’ve come to expect and SciFi elements, the film doesn’t lose focus on its emotionally involving core. Both versions of Todd have hurt people in their orbit in significant ways, and each one will need to travel to another plane of existence to try and set things right.
