Plot hole: After Cali's father is killed the decision is made to cut power to the school so he or his men don't find out about his father. But if power was cut to the school then what is powering all the machinery in the kitchen that's providing food for 90 students?
Plot hole: In the first film, Toulon fled to America and, when the Nazis found him, committed suicide in 1939. But this movie, effectively the prequel to the franchise, opens in 1941.
Plot hole: The pipe bomb that Maggie uses to kill Freddy is the same one that was found in Spencer's room earlier in the film. It's already been established that Freddy was erasing the people he's been killing from existence, so that pipe bomb wouldn't be there to use on Freddy.
Plot hole: When Dr. Marvin is trying to get Bob to leave the night before his television interview, he can't leave because it's pouring rain. He also can't drive him because their car was left at the boat dock. However, Dr. Marvin could have easily called for a cab to drive Bob back to where he's staying.
Suggested correction: This assumes that there is a taxi service in the small town in which they reside.
This is obviously a tourist town, which would likely create the need for a taxi service.
It also seems to be a fairly secluded and very rich tourist town with cars almost necessary to get around.
Suggested correction: At that time of night in that condition, I highly doubt calling a taxi cab would be easy, especially since Bob lives right down the road, no taxi far away would come just to drive someone a short distance like that.
