I most certainly can, leo oh leo (you're right here beside me, ya know)
The first point is maybe my weakest...cause I may be wrong. But to my knowledge, this was the first 'black' musical to deal with color issues within that minority (light-skinned black vs. dark-skinned black...soul sound vs. smooth 'whiter' sound). It did so in a way that made it accessible to everyone.
second, it is the most fully-successful 'pop opera' we have. The score achieves a robust Broadway sound without ever bastardizing the pop music that is its source. For me, there was always something odd about Jesus or Jean-Valjean singing so 'pop'y. And the music in RENT never fully achieves a true rock sound. DREAMGIRLS tells the story of that time through its music. It's a wonder of a score.
This show also proved that serious themes can still be discussed in a show that has a sense of humor and is very entertaining.
Finally, Michael Bennett's staging proved that theatre could be as visually striking and as fast-moving as film. A quarter century after the fact, WEST SIDE STORY finally found its descendant.
