Memorial Day has come and gone. You know what that means: It’s summer blockbuster time. Moviegoers can now look forward to three months of aliens (Prometheus), explosions (Battleship) and superheroes (The Avengers). And while the summer’s biggest ticket-seller of all time is still The Dark Knight from 2008, it’s hardly a runaway in terms of popularity. Among the competition are Spider-Man, Jurassic Park and Independence Day. What’s the greatest Summer Blockbusters of all time? Only you can say.
