I highly recommend "Underground" just because it is pushing the boundaries of indie action films where it needs to go. It is a true inspiration to see something so raw and creative get made just through discipline, and pure will power....Don't get me wrong I love big budget Hollywood blockbusters and some of the stylized wire choreography of todays action pictures. However, the grit is being lost in some of these movies. "UNDERGROUND" without overstating, gives you a glimpse at a direction that action martial arts movies could explore at the same time a reflection of movies like "ENTER the DRAGON" & the Chop Soki movies of the 80's...
