No pun intended - this starts off as a movie about infidelity ... in more than one sense (and I really like that it is not one sided) ... but it evolves in something more (sinister) ... again no pun intended. So as you can guess with a subject matter like that, there will be quite a lot of nudity.
You can't be too sensitive about this - and generally have an issue with intercourse of course. This really does tests the line between soft and hard core. There is nothing really explicit (as in showing actual penetration), but it gets really close a lot! But that is not the main selling point of the movie. Or at least I think there is more to it.
Now if they had a bit more work done on the script ... I think it could have been even better. Really interesting and quite topical theme ... the acting is a bit rough to watch ... but it does work overall ... even if you may wonder from time to time, why character act the way they do ... seen worse to be honest, so I was ok with however the movie approached things ... just suspend your disbelief and just ... come as you are! Satisfaction (sort of) guaranteed.
