If enjoy for example, the filmography of Takashi Miike but want something a bit more sophisticated I would advise you this is a must see. On the spectrum of those type of 'shock films', I would actually rate this a 10 star rather than an 8.
It is probably the most disturbing Japanese film I have seen, and despite what the movie poster suggests, that is accomplished without any graphic depictions of sex, violence, or gore (excluding the last scene). All this to say, it is a very intense movie that left my jaw hanging open throughout the entire viewing thinking "What the f***? What am I watching?". Great movie!
