"Travis seems confused. He is so much part of his own world, he fails to comprehend another's world."- Paul Schrader, TAXI DRIVER
Do you remember that scene in TAXI DRIVER where Travis Bickle finally lands a date with the woman of his sick fantasies and decides that taking her to a Swedish porno film in Times Square is just the ticket to win her over? When Betsy balks, all Travis can do is scratch his head in befuddlement. "These are the kind that couples go to," he protests. "Honest. I've seen them."
That was an unsettling little scene, right? Well what if Travis Bickle were painted by Schrader/Scorsese/DeNiro as just a loveable, misunderstood galoot? And what if Betsy just rolled her eyes, shrugged her shoulders, and said "here we go again!" or something and accompanied Bickle into the theater?
