Query: Decent movie, great guitar work!

The plot of this movie is interesting, if not a bit shallow and clichéd. The acting is mediocre as well. Like "The Blues Brothers", what makes this movie great is the soundtrack. Ry Cooder plays some excelent guitar, and I must admit that Ralph Macchio does a very convincing job mimicing the guitar parts on screen (perhaps that's why he got the part?). This is a great movie for blues fans in general and especially those interested in Robert Johnson and the Delta blues. Even if your not a blues fan, the guitar parts in this movie (especially the famous "Duel Scene") are worth the price of the movie. I watched the duel over and over again and it made my jaw drop every time.
