>>1669977Watch the movies independently from the TV series. The two take place in different continuities. If you prefer TV episodes, watch SAC first, if you prefer movies, watch those.
TV Series:
GitS: Stand Alone Complex (SAC)
GitS: SAC 2nd GIG
GitS: SAC - Solid State Society (SSS).
In that order.
Movies:
GitS (1995) - This is a classic, a must watch, preferably in 1080P. This also follows the manga before it splits off.
GitS: Innocence - Not as good as the original movie but I enjoyed it. I'd save this for last, just because.
Then you have ARISE, which is an ongoing 4 part OVA that is a prequel to both the movies and SAC. The next episode is to be released on June 28th.
