The concept of the plot is a smart one, but unfortunately, nearly everything in the movie hinges on the fact that the protagonist is stupid. The struggles the main character must endure are mostly born from ill-conceived or rushed plans and a disability which swings wildly from moment to moment. In one scene she can barely lift her arm and in another she has a much broader range of motion which would have instantly trivialized or outright solved the problem before it. Beyond these obvious problems, the main character isn't particularly likeable. Her bad choices (including her barely explored and later, self-excused, backstory) are grating after about the third or fourth obvious plot-forwarding screw up. On top of all of this, without getting into spoiler territory, much of the setting just doesn't make sense. Why is the radio battery-powered when the house clearly has electricity? The doors are semi-handicap-accessible and stairs entirely rebuilt, but no effort was made for water access? Overall, this is worth a one-time watch if you're anxious for some middling horror, but don't expect any real thrills or frills from this film.
