Perhaps this soundtrack has been reconfigured so much that you forget it's just a soundtrack? This remix album aims to get Tron on the dancefloor and it certainly succeeds. Anyone who found the original soundtrack to have a few highlights but nothing more should definitely give this a spin. It is unfortunate that not every track on the original was remixed, but each remix is quite unique so that you won't really mind if there are two remixes of End of the Line, etc.
A variety of artists get a chance to give us their take on the TRON: Legacy soundtrack, and it works. Each track is unique and remixed quite well. My favourites are The Son of Flynn (Ki:Theory remix), and Adagio for TRON (Teddybear remix).
