There's simply no getting around how much of a disappointment this turned out to be. The storytelling felt disjointed and lacked focus, ultimately delivering nothing worthwhile. It chronicles the experience of an incarcerated individual navigating unfamiliar surroundings within a confined space, but offers almost no background information—just a slow descent into madness portrayed in a remarkably dull fashion. This leaves the audience feeling as though they’ve been taken on a chaotic journey that leads to complete emptiness. If someone were to inquire whether or not I'd recommend it, my response would be far more straightforward than whatever point the film was trying to make: Don't bother.
