The 'SAW' Trilogy Reviewed in Brief
The Guardian's John Patterson (Rated: Cranky) hasn't seen SCENES OF A SEXUAL NATURE or SAW III, but that hasn't stopped him from getting his bitch off over the MPAA's tell-all, explain-nothing film ratings and classification system.
Here is my annotated MPAA-type guide to the SAW movies.

SAW (2004)
Rating: R
For strong grisly violence and language.
Edited for re-rating. Previously rated (NC-17) in (2004).
Translation: R-rated version? For wussies.
SAW II (2005)
Rated R:
For grisly violence and gore, terror, language and drug content.
Translation: Less grislier, more druggier. Also, terror. If you consider flashbacks terrifying.
SAW III (2006)
Rated R for strong grisly violence and gore, sequences of terror and torture, nudity and language.
Translation: Same shit as first two. Plus: boobies!
After the jump, experience a moment from SAW III.
Here is SAW III's nudity interest (left) in a scene with a clothed male actor (right).
