Continuity mistake: Julie talks with her mother in the kitchen while her father stares. On his glasses, only one person is reflected. Uploaded picture has been zoomed to illustrate the mistake, but in no way is necessary when watching it on a screen.
Suggested correction: 1) The fact that you have to zoom in on the image invalidates the error. 2) In the image, I see a silhouetted figure against a bright light source. The second person could very well be to the side and therefore not visible.

Continuity mistake: When a beast is about to hit Kevin, Evil-Lyn shows up, raises her hand with two fingers pointing upwards and commands to spare his life. A shot later, her hand is now pointing at him.

Continuity mistake: Lubic sees the pink car zoom by a tree and a bench. A second later, it passes by again.

Continuity mistake: When Kevin is cleaning up in the kitchen, he puts a load of Burger King related rubbish into the sink. In the next shot as Evil-Lyn enters the kitchen, the sink is now empty.
