Jaws is generally recognized as an amazing film that basically created the summer blockbuster movie model. Summertime was not traditionally the time for audiences to stay indoors to watch movies, and Jaws changed that.
The Jaws sequels don’t have any positive reputation at all. Jaws 3 was in 3d, a fad that died a pretty horrible death in the 80s, and Jaws 4 was reviewed as one of the worst movies in memory. But that leaves Jaws 2 as kind of a middle child that got lost in a shuffle. Not fair.
