Since the beginning you can understand what the movie's about and the introduction is a good touch on the main story which is good all until their friend Kelly comes and they all go to the greenhouse part of the house, when her friends go searching for another candle after Kelly's one blows out they see the doctor and they stand around talking with him nonsense for who knows how long as if they totally forgot about Kelly and they come surprised when they find her dead hours later.
Another scene before the ending with Miles when he checks the time but finds out that the Midnight Man used his trick, so then he comes and Miles just stands there watching him immobilised waiting to die even though he had enough time to go back to his salt circle.
These were some minor things but they were really frustrating and ruined the mood of the scenes... I think a fan of this movie and the creepypasta should also check the game which is a bit old and made with Unity but it's very nostalgic and reminds me of the Slenderman days.
