I've seen parts of it and holy god is there a lot of rape in it.
Not really; there's only three instances of rape in the film.
1: Billy Boy and his gang making an attempt early in the film.
2: Alex and the droogs when they attack the writer and his wife.
3: The staged rape film during the Ludovico treatment.
Of the three, the first one is a failed attempt, the third one isn't real and the 2nd one is merely implied, although enough to deduce that it actually did occur.
Aside from that the only other depictions of sex, whether the act itself is shown or it's just an implication, is Alex taking the ladies from the record store back home, Alex's vision of the biblical hand-maidens and the final shot of the film.
It's funny how the permeation of an idea or of tone and content can make one think there's more explicity than there actually ever is.
Like how critics condemned the original "Halloween" for violence when in fact there's hardly any violence in the film whatsoever; it's simply the construct of violence seeded by Judith's death, which is furthest the violence ever goes in that film.
Sorry for ranting.
You guys need to go watch more movies.
There. There's a contribution to the intent of the thread.
