Not an especially good film in many ways (for instance, the tiresome Christopher Walken) and yet some of the clothing (and other visual aspects) are worth a look, are they not?  (Did agents of the FBI really dress that way, so that every bad guy knew exactly who they were?).  I quite like some of De Caprio's early college boy clothing (but is it 'Ivy League'?).  Visually, elsewhere, I'm reminded of some parts of 'The Godfather Part 11.  And the music?  Well, Friedwald had, for no apparent reason, little time for Astrud Gilberto.  Personally, I could have done without The Kinks. 
But look at Dicaprio (got that wrong the first time ^) on the cover of the DVD.  Not bad.  Not bad at all.
