Which is the best series comprising only 2 films?
Often times when a film gets a sequel it becomes a full blown franchise. (Often at least a trilogy) But here is the sets of films where they (at least for now) have only gotten one further installment for one reason or another. So this is just to see which duo of films is considered the best. Remember, these are all films that are supposed to bet set in the same continuity. Some of them for instance are being considered to be rebooted and the like. And also remember that you're supposed to take into account your feelings for both films in each set, whether you like one of the films or not. As this is a test of the films' accumulative strength against the other films duos.
