The film is about capturing a killer shark that feeds on humans. It's a spectacle to be seen on the big screen. The first half or three-fourth of the film is about planning how to go about capturing the shark. The last part is all in the sea. It's an amazing film because the way it traverses from scene to scene. The film involves a lot of character build up and a basis for the shark to be killed. It also keeps minimalistic in sound and gets loud only when needed.
The sound design and the music by John Williams is a study in itself. The editing is precise and keeps the movie gripping. To be fair, there are hardly any dull moments in the film, even though the end is known. The journey is so interesting that the destination feels like a by-product of the journey.
Steven Spielberg grew in stature with this film. I am told by my uncle who saw the film in theatre 1970's when it got released that it was indeed a phenomenon and one of his friends does not enter into the water even today that is 40 years after seeing the film he is still afraid of sharks. Though funny, it is indeed true and confirmed by the person itself.
It's impactful and must be revered for the change it brought about in mindset and understanding of the sea the nature of sharks.
Acting is stupendous and though I don't know any of the cast, they played their roles superbly and are heroic in their own ways.
A 4/5 for one the great films ever made, though it lost it's aura a bit as technology got updated, it must be seen for the content.
