All science-fiction can be roughly divided into two types of nightmares. In the first the world has gone through a nuclear holocaust and civilization has reverted to a neo-stone Age. In the second, of which ""Rollerball"" is an elaborate and very silly example, all of mankind's problems have been solved but at the terrible price of individual freedom. ... The only way science-fiction of this sort makes sense is as a comment on the society for which it's intended, and the only way ""Rollerball"" would have made sense is a satire of our national preoccupation with televised professional sports, particularly weekend football. Yet ""Rollerball"" isn't a satire. It's not funny at all and, not being funny, it becomes, instead, frivolous.
