Query: The best shark movie ever made.

"Jaws" is the best shark movie ever made and it is my absolute favorite movie of the 1970s. It is also a big hit at the box office in 1975. A police chief (Roy Scheider), a sailor (Robert Shaw), and a marine biologist (Richard Dreyfuss) ride on the boat, called the Orca, to kill the giant great white shark, that had eaten some people on the beach in Amity Island. The fact is that this movie is rated PG. It should have been rated PG-13 because of the violence in it and it is not a movie for younger kids to watch. But, it is a cinematic masterpiece. I have "Jaws" on DVD and I am happy to own it. A must-own for your DVD player.
