(No gore, despite what it says below. Profanity.)
My thoughts on this short film after the cut.
Of the five characters, I only considered the youngest girl the true protagonist due to her natural caution and lack of desire to cause some element of strife. She expressed pure fear as it wasn't diluted by the jaded, disillusioned teen years (which the other characters wore so prominently) and made her final moments so desperate. It was a nice touch.
The monster here is open to a bit of debate as it is never seen. Analysis of movement/attacks reveal the trigger mechanism, the increasingly ominous, charred light switch, as the source but that seems more to house the aggressor than be the danger itself. We are given enough information to notice the timing of events; the victim is present for the switch off and remains present in the dark, but in that miniscule transition from dark to light is the only time the attack happens as demonstrated by the dropping of the soccer/football and the hand-holding scene. This offers an uncommon twist to the fear element as the viewer realizes that the danger may not actually be the dark (though it signals the danger), but rather the light (as the element of timing suggests it to be).
The unknown element here is whether the entity gained strength by taking each of the children, allowing it to manipulate the light switch on its own, or if it could have done so in the first place and simply let the protagonists be lulled into a false sense of security with the illusion of control over their environment. Reviewing the film, the light switch itself does not change in any way after the disappearances, only the protagonist's perception of it as the source of the threat, so this is just speculation on my part.
While I'm not sure how an abandoned building like that still receives electricity, I will say that it was a nice choice for the setting. Abandoned military academy, perhaps? I didn't notice any specific building listed in the credits to give me any indication aside from being shot in Keighley, West Yorkshire, but it certainly has the feel with the grand front and wire fences and the inside set was appropriately spooky with light/shadow play and rotting debris.
My biggest gripe here is my inability to understand what the kids are saying to each other. No, the dialogue didn't convey any crucial details, and I know that I'm notably bad with thicker English accents (I often have to ask Beemer for translations when watching certain BritComs), but it just seemed like the audio quality was a bit muddled. Then again, I suppose it doesn't really matter as the only sound that needed to come through clearly was *click*.
