The Electricity Thing?
potential mini-spoilers ~
I found the creatures very Lovecraft -
I also wonder why, other than the brief use of a lighter, folks didn't think about using fire instead of relying on electricity, when they know that the creatures can't abide light and that they are capable of fritzing out electronic devices.
I did miss a few minutes of the film...no one thought to use fire, right?
