Slick. Romanticizes music as much as it does young love. I'm convinced that Edgar Wright makes musicals out of his movies, conducting the action like a madly passionate maestro. Satisfactory to exhilarating car chases and gunfights, wonderful and clever use of setting to deepen appreciation for audiophiles and a tourists sweet ode to a city. Never a lacking moment, always progressive movement. Never look back.
Too much? Not enough? Asking these questions means you watched something worth admission. Usually, anyways. Definitely this time.
UPDATE: "Noir with a heart of gold." Absolutely. Movie - you just got a new star added.
