Continuity mistake: In the scene where the Pin and Brendan are sitting on the beach talking, in one shot the sun is below the horizon, in the next shot it's just above, and in the next shot it's under the horizon again.
Continuity mistake: After Brendan throws the clock at Kara's mirror, there is a shot of Kara with the broken mirror behind her. Brendan is shown backing up into the doorway. But if you look at the doorway in the reflection, you'll see that Brendan is not there. And in the next immediate shot, he instantly reappears.
