If I had to pick one movie that completely changed what we think a thriller should be — I wouldn't even hesitate. It's definitely "Jaws."
June 20, 2025 marked the 50th anniversary of Steven Spielberg's iconic film. Half a century since the movie hit theaters and changed Hollywood forever. "Jaws" literally created what we now take for granted — the summer blockbuster.
But strip away the flashy headlines and historical analysis, and you're left with simply perfect cinema. One of those rare films that still has you glued to the screen decades later, forgetting to blink.

Fun fact: the fear has (mostly) faded with age, but as a kid I spent ages begging my parents to buy me a dorsal fin like a shark's so I could play with it in the bath.
Sure, movies today are packed with amazing graphics that cost millions. But even now, few filmmakers can play with an audience's nerves as skillfully and subtly as Spielberg did in 1975.
The camera slowly closing in on a swimmer, the haunting rhythm of John Williams' legendary score, and the shark's absence from most of the film — that's pure magic.

One Rotten Tomatoes viewer summed it up perfectly:
Hard to argue with that. Fifty years later, "Jaws" still keeps us on edge. Still hits those emotions. And it's still my absolute favorite thriller. Earlier on zoomboola.com, we told you about "The Shooter" — an action flick you definitely missed in the '90s.Viewer named Tim M. from Rotten Tomatoes"Jaws is the main reason the summer blockbuster phenomenon even exists. This is the movie that makes me afraid to go into water where I can't see the bottom. It's possibly the greatest horror film ever made. It deserves to be on the Mount Rushmore of American cinema. And its soundtrack is one of the best ever created for the big screen."
