The only supernatural Jaws in the series

Apparently, the shark in this movie is the ghost of the shark that Brody killed and it's back from the dead for revenge. It killed Sean and followed the family all the way to the Bahamas to get them because it has ESP. It's very odd they would go this direction in the series and make the fourth one supernatural. I don't know how they could've possibly thought this was a good idea. Not only do I blame the writer, I blame everyone else, from the director to the producers. They should've never let this happen. It wouldn't have been as bad if the shark was an entirely different shark and not a shark that was back from the dead and going after the Brody's for revenge.
