This is an intelligent film whose full layers will likely not reveal themselves in a single viewing. There is a lot going on and the rules of engagement are bizarre yet internally consistent. This is a film made cheaply, but reliant on smart writing and good performances to deliver quality. Scares may be few, but the horror is profound. There is existential menace and cosmic horror at play at a level where horrible death is a preferable option. The dual leads are also the writers/directors which is normally a warning sign, but respect to levels of talent, as their easy charisma caries this film. There's humor at play, but for the most part this movie is introspective and thought provoking and the core mystery delivers. While well executed on a slim budget, there are certainly holes in logic and seams where the budget shows, but for what it presents, it presents exceptionally.
