A lot of reviewers are calling this film an instant classic, and if studios were capable of making good decisions—which, let's be honest, they aren’t—they should definitely make another volleyball movie. I don’t consider it an instant classic myself, though. But I do think it’s a fun, entertaining B-movie. And I get the appeal of the volleyball element. I grew up in a small, struggling town in the Midwest that was hurt by NAFTA, and among kids there, volleyball and Ultimate Frisbee were popular activities, as was disc golf. Volleyball was really big; we even had a bar built around it—seriously! You needed something to play with, right? All the Sandlots were full of children, football was too structured for casual games, but you only need four people for volleyball, so it’s easy to find players. I can't accept the idea that someone from the Midwest wouldn’t know how to play volleyball; I just don't buy it. I could believe he isn’t used to playing on sand, though. Hollywood seems to think the Midwest is just Chicago and a bunch of people who only recognize corn and the kids who live there. If you consider films like "Over the Top," "Airborne,” or “Karate Kid”—movies about someone new to a place who wins over others through their skill at something—then this film follows that formula. Or, at least, it has half of it. The other half is basically an extended version of the volleyball scene from “Top Gun,” but with worse music.
