The Visit (2015)

Plot hole: When they left the camera out overnight to film Nana it would have had to be recording all night. A DSLR will not do this and does not do motion detection either.

Trivia: While the film was always meant to be something of a horror-comedy, director M. Night Shyamalan supervised three versions of the film during editing- one played mostly for horror with little comedy, one played mostly for comedy with the horror downplayed, and one that tried to balance both tones equally. The version that balanced horror and comedy equally is the final version released in theaters.

Question: Why didn't Loretta call 911 instead of just the Masonville Police station when she learned the two people her kids were staying with were not their Grandparents? In the event of two escaped psychopaths holed up in the house with two vulnerable kids, police would have connected the dots with a SWAT team, probably called in to rescue them. Tyler and Becca being in the house with the two unpredictable, deranged killers was basically the equivalent of a hostage situation.
