A 2005 made-for-TV movie following after "Ghost in the Shell: Stand Alone Complex" season 1 and season 2. The events happen a couple years after the end of season 2, with the Major having left Section 9. Aramaki has promoted Togusa to replace her as the leader. The primary problem they try to deal with is the systematic abduction of hundreds - or maybe thousands - of children ... and possibly by a government agency.
While it's not disastrously bad, it's the weakest entry in the series so far. Kusanagi's motivations have always been opaque, but seemed to have some logic: now they seem opaque and lacking any sense. And the logic gaps the writers leap freely over (mentioned in my review of season 2) seem to exist in particular abundance in this movie - perhaps because of the relatively short run-time of 1h40m.
