17. 'Jaws 2'
Say what you will about Jaws 2, but it had maybe the greatest tag line in the history of cinema: "Just when you thought it was safe to go back in the water." Unfortunately, that was the only good thing about the movie. Steven Spielberg wisely didn't come on board and Roy Scheider wanted absolutely nothing to do with it, but he was under contract to the studio and they gave him an absolute fortune. The budget was enormous for the time, but the plot was quite familiar: another shark starts killing the people of Amity Island, the mayor doesn't want to close the beaches and Chief Brody is forced to kill it himself. As horrible as it was, the next two sequels were infinitely worse.
