There are two constants in the Jaws franchise: each film contains a giant great white shark and in each film members of the Brody family are terrorized by said shark. The third film in the series, which debuted during the brief revival of 3-D movies in the 1980s, shifts locations from Amity Island to a Sea World park. Dennis Quaid plays Chief Brody's grown son Michael, a Sea World big shot, who once again has to face great white terror after a shark gets locked inside the park. I can't imagine how anybody at the actual Sea World park thought it would be a good idea to let them make a movie wherein a number of patrons and park employees are brutally killed. The only way you're likely to see this movie today is in its current 2-D home video version, which renders the 3-D efforts comically anticlimactic.
