The idea of a man-eating shark is so frightening and interesting that an entire narrative can be formed around it. In fact, just about every movie that features a shark, outside of the animated kids film "Shark Tale," portrays sharks as vicious, blood-thirsty creatures. Monster sharks have been used to lure viewers to the theater for years now, and the six films on this list feature the most notorious sharks who developed a taste for human blood.
The 1999 action horror shark movie "Deep Blue Sea" has some of the best special effects of any of the shark films on this list. Highlights in this film include Samuel L. Jackson getting gobbled, and a whole plethora of sharks attacking people, instead of the solitary sharks in the "Jaws" franchise.
Not as good as the original but still good for a sequel, "Jaws 2" not surprisingly has a movie shark who develops a taste for human blood and is the focus of the entire film. Hopefully that wasn't a spoiler.
This realistic and scary independent shark film has two people stranded in the titular open water surrounded by man-eating sharks. As you can probably surmise these movie sharks develop a taste for human blood and terrorize our main characters.
"Megashark Versus GIant Octopus."
Anything called Megashark must be a movie shark who developed a taste for human blood, otherwise the giant octopus would obviously win and this wouldn't be a movie worth barely watching. Fortunately, the Megashark eats just about everything; unfortunately this movie is still garbage.
"Shark Attack 3: Megalodon."
The Megalodon, which is evidently the biggest shark to ever exist, is a movie shark who developed a taste for human blood in this godawful waste of money. However, it's fortunately so bad that it's worth watching. Once.
