Both the start and end of this movie are insufferable for totally diferent reasons.

The opening hour is some of the worst acted, found footage set-up I've ever viewed, leading me to almost bail out at multiple points. Only this movies notoriety online kept me going to see what all the fuss was about. I would strongly recommend watching the opening hour at 1.5x speed if available, you'll still get the nuances of the characters, but the scenes will not linger like they do at normal speed.

But ff you can make it through that initial hour, Megan Is Missing features one of the most chilling, dark and terrifying endings in horror I've seen for a while. Is it torture porn? Basically, but it's ruthless approach really made my stomach drop few times, which is all I can ask for from this genre of horror.
