Continuity mistake: Maddox has blue eyes as a teenager and dark brown eyes as an adult.
Revealing mistake: The "Anamika Resort" van isn't quite in sync with the road it is supposed to be traveling on. A side view shows the van is traveling straight ahead, but a shift to a front view shows the road behind the van is curved to the right. The same thing happens a little later, except the road is curved to the left. (00:01:19)
Other mistake: How did Trent (who started as a six-year-old) end up with an adult-size watch and bracelet?
Answer: Because she was 'freshly' dead when she hit Trent.
