Just an experiment

I see a lot of people here who are cussing out the events in this movie. Saying that a mother and son having sex is wrong. But I also see others who see it from another side, who see it as a completely reasonable act, and in some cases even more hot because she is his mother. We all have our own opinions on this, but what I'm doing here is simply asking everyone and anyone who happens to stumble across this to write down there opinion here, and try their best to justify it.
