There is a scene in this movie that everyone picks on. I think this bugs a ton of people, and I think I solved it. This is in my opinion what really happened.
This will
contain spoliers of some Friday the 13th movies, so please don't go any further if haven't seen them:
Jason is on the big boat (Lazarus or something), and than the people leave the boat on a row boat, and than after they row the boat all the way to the shore of New York City, Jason just suddenly appears in the water, and goes up the ladder. Well, this has puzzled people, and I think because of this scene, many people might hate this movie.
Well, my suggestion is that Jason took a rowboat. I know many people probably think??
I know there was only one rowboat on that cruiseship that we see, but maybe on the other side of the boat, there was another one. Maybe, that's why Jason never went down the ladder to get them. He figured they would be gone by the time he went down, and he saw there are no other rowboats on that side of the boat. Surely, a cruiseship has to have more than 1 rowboat. I remember watching a movie, and a rowboat was even on board, and they threw it over. I don't know what that movie was.
So, why didn't they show another rowboat, or him going after them the whole time. It's because these movie likes to surprise people. What fun would it be for us to see Jason going after them in a rowboat anyway? The other 2 explanations could be he swims (but I like this one because he's afraid of the water- he drowned), and the other way is maybe he went through a sewer line (like at the end of the movie).
I can't take the thing that he just transported himself from position a to position b. If that was true, why didn't he surface in New York before they got there.

Now, the only question about this movie that I have in which someone can help me figure out is why kill the principal. The rest of the people make a lot sense to me. The camp counselors killed Jason by not rescuing him, and the camp counselors killed his mother so he goes after anyone that resembled camp counselors or even just regular teens because he blames that group of people for doing one or the other. He doesn't go after kids like the 6th movie.
He also will go after people that threaten him like in the 6th movie he goes after police (with guns), paintball people (with weapons), this movie (the guy with a knife), the cruiseline captain (because he wanted to sink the ship), the gangster in this movie (because he wanted the girl), but I just can't figure out the reason for the principal. When he was killed he was sitting in a something (I don't know what.).
Maybe, the reason he wanted to hurt the principal is because he knows that the girl was pushed in the water by the father.
