Batman Returns didn't make as much money as they wanted either. They didn't kill the franchise right then and there. Even with the backlash it got. As for critical reaction, since when has that ever stopped movie companies from making sequels lol? The amount of movies, comic book and non comic book ones that have had sequels to movies that were panned by critics is astronomical.
Being a Batman brand name didn't make it instant success. Batman and Robin is proof of that.
