Instead of having crappy sequels..

It would have been so much more mathematically satisfying, and perhaps more economical, to have them all condensed into one huge Superjaws sequel.

Or perhaps even a Jaws Prequel? Teenage College kids and screaming, dumb scantily-clad College girls all avoid baby sharks whilst saying 'dude', 'man', 'cool' and 'like' a helluvalot?
