The absence of Matt Damon in this program/movie confused me because it came out after the first Bourne Identity in 2002. I have only seen the four versions, Legacy, Identity, Supremacy and Ultimatum.
So, At the time I view it, I could never figure out what was going on and lost track of the story line. So, I would give it a low rating of all the TV series of the other three that I was able to view. If you are a Matt Damon/Bourne fan, as am I, I recommend that you not waste time watching the Legacy version
