I really liked the movie and thought the disc was pretty good, too.
You may want to check out if the one you are getting is the two-disc version or not (The second disc contains the feature-length documentary "Wadd"). When it first came out, I bought it not knowing it was a two-disc and the feature on the second disc was listed nowhere on the box (nor did the box say anywhere that it contained two-discs). On the front it had a sticker that said "two-disc limited edition". I don't know if that means that it would later be phased down (easily) or if it meant "limited edition" in the "Saving Private Ryan" sort of way.
I definately recommend this. I got the 2nd disc - even though there was no reference to it on the packaging. I'm thinking that this is the case because the documentary on the 2nd disc was produced by VCA - a porn production company and they didn't want to cause controversy.
Yeah. The documentary on the second disc is an R-rated version of it, as opposed to the NC-17 version. Which is pretty funny, because they included the friggin crime scene video on the first disc. I still can't believe they did that.
