Sayles sprinkles some timely 60s Motown and rock n roll into the scenes and also adds in some 70s Springsteen fare that help to give the film an authentic texture. He absolutely nails the scene in which they take a weekday trip to the deserted boardwalk. Also the argument in the dorm stairwell is brilliant in its simplicity and reality.
Baby It's You has sort of an independent film feel to it, which of course isn't unusual given that Sayles made his bones with excellent stuff like the Return of the Secaucus Seven and Matewan. Do not miss this one, it's definitely one of the best love stories ever.
