Wow... kinda a tall order. I have seen one of the mangas, the first movie and as much of the TV series as has been released in the US on DVD.
As far as I know there are: 2 mangas, the original and Man Machine Interface; 2 movies, Ghost in the Shell and Innocence; and a TV show with two seasons. There are also at least 2 video games.
All of these have different ratings. I will review Man Machine Interface, the first movie, and the first three discs of the TV series.
Man Machine Interface first. This is the second manga series. I have not read the first one. The female costumes in this are skimpy at best and skin tight/non existant at worst. There are a lot of opportunity shots as well. There wasn't a lot of cursing in this series as far as could see. The plot is odd cyberpunk as is usual for the series, I wasn't able to get beyond that due to clothing problems with the charachters. There is drug use but it seems to be portrayed in a negative sense.
I cannot recommend this on a good conscience due to the large problems with nudity.
The first movie is known as a classic... i have not seen it in a while but it does face the same issues as MMI, since the main charachter must be nude to use their "cloaking" device, and it is used quite a bit. There is blood and gore in this series, due to several gunbattles. There are also some strange scenes with some odd ascending beyond normal humanity conversations and metaphysical connotations through out. Charachters arn't very deep. Storyline is odd and apparently follows the first manga. I can only reccommend this to mature individuals due to the content. Also look here for more opinions>>>

The TV series is much cleaner. For reviews I will reference you to several other threads.

I will make the note that there are some very disturbing scenes (severe torture/pain) in one of the episodes on the third disc... along the lines of Saving Private Ryan D-Day/most disturbing ep of CSI you could think of/Full Metal Jacket/Clockwork Orange. the first 2 DVD's were 13 and up...3rd is 16 and up, specifically for that episode. I reccommend PMing me for details if you are curious, since I will not post them, and, if you are sensitive to that kind of thing, not watching ep 10, since it is a stand alone episode on Batou's background.
