Quick paced yet insightful, Daley's novelization of the film is much better than I would have expected. Despite stripping away some of the most noteworthy aspects of the TRON film, namely the groundbreaking special effects (for 1982), the stellar sound effects and sweet synth of Carlos' score, the author handles the basic necessities, while bringing into the book what films rarely can: internal dialogue. The recaps of the action are exciting, the descriptions of the computer world are apt enough and don't slow the story down - you can imagine enough of what's going on without long-winded descriptions. The addition of knowing what the characters are thinking is key and very well done. There's just enough drawn in that explains a look that either Flynn, Sark or Tron might have had on screen, and in many cases this rounds out the characters a bit.
All in all, while you can read this on its own, it's doubly effective if you know the movie, or (re)watch it afterwards. Both are deeper with the other, but if anything, this novel proved to me that the original film wasn't all CGI/sound fluff, there's a fairly solid tale to be told.
