Avid fans of the original Tron (like myself) have likely anticipated the release of Tron: Legacy since the day the first hints of a remake appeared in 2008. A lot of pressure was on the Legacy filmmakers to not only keep the original sense of wonderment and otherworldliness of the first movie, but also bring the technology and ideas from the first movie into the twenty-first century.
The short version of this review is: you should see this movie. It is a great homage to the original, and it has enough digital effects, and just enough plot (just like the first one—the plot was never a strong point!) to keep your eyes on the screen.
