I'll add Donnie Darko and The Blues Brothers (that may be cheating, though).
Every scene has a place. Every exchange has a quotable line.
The soundtrack, however, is like the Library of Congress authorized the American Anthology of Awesome Blues, and hired God to produce it.
From Wikipedia: "The Killing Moon" by Echo & the Bunnymen was replaced with "Never Tear Us Apart" by INXS, which Kelly had not had the rights to use in the film's theatrical release.
Also: Kelly had originally wanted to use the songs "Never Tear Us Apart" by INXS and "West End Girls" by the Pet Shop Boys during the opening scene of Donnie cycling home and Sparkle Motion's dance at the talent show respectively, but financial constraints meant that he instead had to use "The Killing Moon" by Echo & the Bunnymen and "Notorious" by Duran Duran. For the director's cut, Kelly was able to gain the rights to use "Never Tear Us Apart" for the opening scene, and moved "The Killing Moon" to later in the film; "Notorious" was not moved from the talent show scene.
For Blade Runner director's cut, I had mixed feelings. The unicorn scenes and some other added footage helped. I thought getting rid of Deckard's inner thoughts VO was a mistake.
In the scene at the noodle stall, it clarified a lot of things such as the language people were speaking. The VO after the dancer's shooting was also revealing in a way that interpreting the expression on his face was not.
