I'm not a big Spike Lee fan at all, but in the battle of very cult-following, very environmental directors, Spike Lee stands head and shoulders above the always annoying Woody Allen.

QUALITY:
Pretty decent.  The picture has a little bit of grain, to be expected for a 20 year old movie, but not as much as you would think.

BONUS FEATURES:
Commentary, making-of, behind-the-scenes, featurettes, deleted scenes, extended scenes, a documentary.

This is one of the most powerful and best movies of the sex and slasher filled 80s and shows Spike Lee as a true bonified director early in his career, easily setting a bar he has struggled to meet since.  The bonus features are extremely and surprisingly heavy, with Spike Lee coming back for commentary and to film a new documentary, showing how much this film means to him.  With good reason, Do the Right Thing is well worth the watch and this blu-ray really does it justice.
