A lot of effort goes into the production of movies involving a huge crew that puts in their sweat and blood to ensure that the reel that comes out is good enough to impress the audience. Classic movies like Citizen Kane and The Godfather are exceptional and you can watch them anytime that you feel like. However, at the same time there are some movies that have sub-par production, meaning that the crew has not put in enough effort. There are also some movies in which the crew put in a lot of effort but the result did not come out the way that they expected. Here are some of the worst movies of all time, according to Rotten Tomatoes, the popular movie reviewing platform.

Jaws: The Revenge

Jaws: The Revenge, otherwise known as Jaws 4, is the third sequel to Steven Spielberg’s Jaws, and the final installment in the Jaws franchise. Released in 1987, the film follows a now-widowed Ellen Brody, who is convinced that a great white shark is seeking revenge against her family, even following them to the Bahamas. Unsurprisingly, the film was not received well by critics and was finished at lightning speed in just nine months. The film received a score of 0% on Rotten Tomatoes, with Roger Ebert commenting that “it is not simply a bad movie, but also a stupid and incompetent one.”
