Oh! I can't believe you people out there actually gave this movie any value. I am simply not that kind of person who can dig deep thoughts out of a bunch of crap, who can stare a guy in this movie peeing for 5 minutes without being p***ed off. I watch movie for fun and didn't enjoy at all watching unchanged scenes, empty stairs, stonefaced actors eating, s****ing and sleeping for 115 minutes. Not to mention when the son coincidentally had sex with his dad, i was just completely freaked out. You can name this movie realism or what. But to me that's hardly the reality and completely unacceptable and pervert. I strongly recommend you not to waste the 115 minutes, even though it probably won't be 115 because you will fast forward most of the movie just like me.
