Four friends head to Hawaii to investigate reports of a haunting at an abandoned resort in hopes of finding the infamous Half-Faced Girl. When they arrive, they soon learn you should be careful what you wish for.
@20:20 One character asks another why she believes in ghosts. It leads to a discussion on religion and the afterlife. It's very generalized and doesn't focus on any particular religion. Topic shifts @21:50, convo ends @23:18
@25:25-30:14 Sleep paralysis vs presence of a demon
Kind of. One guy gets his face torn off and his eyeballs are part of that, so if you've got issues with eyes in skinned faces, maybe don't watch that bit.
There is no on-screen death, but the death of a young girl (believed to be between 10 and 16) is the cause of the movie's main antagonist, a ghost. A male voice describes the girl as being hung and left for dead. There is no detail or visual.
Sam first shows signs of being possessed at @1:01:30. He briefly regains control of his body @1:02:55, but is clearly under the ghost's control again @1:03:55.
Right at the very end, Lex takes a photo of the detective who has been interviewing her and realizes that he's possessed.
@1:03:10-1:03:243 Right after Lex says "I'm sorry", hands reach around from behind Sam's head and tear his face off. That audio is somewhat muffled by the musical sting in the background.
*spoiler* the last minute of the movie or so reveals that the main character never made it out of the resort, but the ghost had tricked her into believing she was in a hospital.
Throughout the movie multiple characters can be shown panicking and displaying panic/anxiety attack behaviours due to the physical and psychological stress of the ordeal.
@25:30 One male character strips naked to swim in the waterfall. He is visible from behind until he jumps into the water @25:50, when he briefly spins around to face the camera with his genitals covered. After this his lower body is hidden by water. The other three remove their clothes to reveal bathing suits underneath.
At 53:38:00 - 53:50:00 a girl is trapped inside a vehicle (and has a panic attack). The ghost possesses the vehicle and rams it off an upper floor balcony. The car is not shown hitting the ground.
