Batman: I've come to rescue you from this turgid drama. No one wants to see old people kissing at this time of year.
Meryl Streep: What do they want to see?BIG. Big Budget, Big Stars, Big Effects, and (so the studio prays) Big Profits. The modern summer blockbuster began primarily with three movies: Jaws, Star Wars, and Raiders of the Lost Ark (the Trope Maker, Namer, and Codifier, respectively) and continued on from there, opening up space for films that previously would have been considered too risky or expensive to make: the first Terminator movie, Back to the Future, E.T. the Extra-Terrestrial, and so on. Because the good ones do, in fact, yield Big Bucks, people continue to make them today. Summer blockbusters are often (or are often thought to be) at odds with critics because as a general rule they emphasize flash over substance. Compare and contrast B-Movie, Dump Months, Le Film Artistique, Oscar Bait and Epic Movie (which is usually a high-minded, sprawling drama rather than an action or fantasy flick). Not to be confused with The Mockbuster, no matter how hard studios like The Asylum try. This type of film came of age mainly during (of course) the Blockbuster Age of Hollywood.
