"Krush Groove" features some great performances by Run DMC (including their classic "King of Rock"), the Fat Boys, Kurtis Blow, the Beastie Boys, New Edition, and a very young LL Cool J. Unfortunately, without any real plot or characterization, that's all the film really has. If you like hip-hop circa 1985, "Krush Groove" is worth watching; it you don't, then skip it.
