QuoteIn the summer of 1992, years of pleading and cajoling had finally brought reluctant director, Tim Burton, back for the sequel to 1989's mega-hit, Batman. Warners upped the budget and granted their filmmaker "carte blanche" in creating the movie, anticipating another smash. What they got was Batman Returns – still a moneymaker, but a significant comedown from 1989, and a film scorned by parents' groups and merchandising partners. The response so unnerved Warners that, when Burton merely entertained the idea of doing a third Batman, they were quick to dissuade him from inflicting any more damage on the youth of America – and more importantly, their franchise. Screenwriter Daniel Waters was told by a friend that Batman Returns was "a great movie for people who don't like Batman." That seems harsh to me; if only by coincidence, the film does reflect elements of the comics throughout their history. Plenty of Batman fans like the flick, too. It might be more accurate to say that Batman Returns is a great movie for people who don't like blockbusters, or at least have become exhausted and cynical toward them. There have been other thrill ride films that subvert expectations or poke fun at the concept of tentpole movies, but Batman Returns goes so far as to be an anti-blockbuster.
