Continuity mistake: Not long into the movie, Reni is looking for her dog. Next time we see the dog, it is on her lap in the life boat. Between these two scenes they never show her finding the dog: it just appeared out of nowhere.

Continuity mistake: In part 7, Tina uses her powers to split the hockey mask in two. In some shots you can see the straps of the mask cut into the back of Jason's head, leaving large cut marks. However in this movie when the mask is removed, the cut marks are not there.
