Alternative Character Interpretation: Was Maggie really in league with Powell the whole time? or just brought under his sway by the events of the night? She has a constant vacant smile on her face once she reveals her true colours, and seems to be in a daze, but, when she asks for a blessing, while still smiling she seems to choke the words out, as though she isn't fully in control of her own actions and words.
Heartwarming Moments: While the whole movie has mess of horror, tragedy and despair, there is one shining moment of catharsis at the end of the "real world". The son barely escaped the secret chamber closing, coming on Maggie's dead grandfather, he hears a nearby noise, and assumes the worst. But, upon opening the door, he and Kim collide into each other, then collapse in an embrace. As Kim whimpers, "Is it over?" the son gives a tired but constant nod to let her know that they're safe.
There's really no excusing him holding a pregnant woman at knifepoint, but James had no idea what he was getting himself into when he was lead to the pillhouse, and what he saw undoubtedly broke his mind. He was, however, not in error when he killed Powell, although that didn't last long.
Vincent, for all his aggression towards the entire cast (including Simon at one point), has a sympathetic backstory, so it's understandable why he is the way he is.
Nausea Fuel: The creature effects are ... rather unpleasant to look at. Some examples include Mutant!Beverly being axed and pus oozing out, the mutated Beverly drilling her tentacles into Mitchell's eyes and mouth ...
Nightmare Retardant: The cultists garb is supposed to invoke Faceless Goons, but the end result is rather hilarious group of people in bedsheets with a triangle on their faces, looking like some weird beekeeper costumes.
Special Effect Failure: While almost all effects are done using practical means and are really good, the greenscreen showing empty desert behind Daniel and Allison in the final scene is almost painfully obvious. It's also noticeable that the filmmakers are attempting to give the practical effects some wiggle room by often having the monsters poorly lit, only shown partially or quickly, or shot in jitter-cam - all of the above, in the case of the transformed Bev.
Spiritual Successor: The plot and its ending brings to mind the idea of The Void being an American, actionized remake of the 1981 Italian film The Beyond; a warlock creates a breach between the land of the living and the Spirit World, bringing the dead back to life and the film ends on our protagonist becoming lost in a barren wasteland on the other side.
