Watched this last night with the gf, didn't know anything about it going in.
As mentioned, the actual duel was pretty fantastic. Completely brutal.
That said, the standout moments for me involved Trusting The Science(tm):
-In Act 3, the wife visiting the doctor who's explaining why she isn't getting pregnant. She's low on her four humours, as well as not enjoying the intercourse, obviously
-During the trial, the wife's cross-examination, one of the dudes is also explaining how you can't get pregnant unless you experience pleasure (little death) during intercourse. Another guy continues that line of reasoning to say "Obviously you could not have gotten pregnant if this had been a rape! This is JUST SCIENCE!" in a hilariously superior tone. As if he's explaining something so obvious that anyone should understand it.
I fucking laughed out loud so hard during the trial scene. So fucking apt, holy shit.
