On this special 50th episode of Box Office Banter, we're talking all about four movies with ambiguous, open-ended plot endings. Starting with 'American Psycho, (2000), 'Pan's Labyrinth' (2006), 'Black Swan' (2010) and finally, 'Gone Girl' (2014). Tune in to hear our theories as to why these plot points were left so widely open to interpretation, and what we think should've been the resolution!
