Lo sciame

Suspension of disbelief - you can attach this to the summary line I wrote or see it as detached from that, as a thing of its own. One thing you have to do though: is really suspend your disbelief and detach yourself from the main character. I would argue that almost everyone will have and take issue with the decision(s) she is taking.

Having said that, since this is based in horror, what horror movie does not to a certain degree need you to really let go of things ... try not to overthink it, enjoy the cinematography and the insane development this takes ... it really "nurishes" on that - pun very much intended.
