I'll start by saying I adore all things Ghost in the Shell.
This is a manga retelling of Stand Alone episode number 2, "Runaway Evidence – Testation." The black and white panels are 100% faithfully drawn from the episode, and it seems to be a accurate retelling of the animated episode.
While I really enjoyed going through this, I probably would have had a difficult time following the action, especially the chase scenes which comprise most of the episode, if I hadn't seen animation a number of times. As a GITS connoisseur, I enjoyed inspecting the episode from the vantage points of both manga and animation, and it's a pretty straightforward, encapsulated story line that is simpler than some of the stand alone episodes and the multi-episode stories.
All in all, a satisfying addition to the collection of GITS family of manga.
