As a refresher, there is only one JAWS book, so anything that comes afterwards is not based on that book, the movie credits even say that only the characters are based on the book.
So where does that leave JAWS 2? Well, this movie carries on from the first one, with Roy Schneider returning as Sheriff Brody. His kids are growing up, and Amity is exactly the same as it was before.
Instead of a festival, it’s now condominiums! The Mayor is still ill-advised, and there’s a new shark in town, but this time it’s only Brody who knows what’s going on. It’s a bit rehashed, as the mayor hasn’t learned anything from the first movie and Brody still has his hands full trying to keep Amity safe.
It’s still a pretty good movie, as events play out differently, there’s no hunting party (it’s a sailing party) and the Orca is at the bottom of the ocean. It was a nice follow up to the first movie, but I didn’t care for the Mayor as there was no character development for him like there was for Brody.
