Should I let my 7-year-old son watch 50 Shades of Grey?

My opinion is, if you let your seven year old watch 50 Shades of Grey you aren't an irresponsible parent. Children of that age need that kind of knowledge.

I truly hope this is a joke question. The content of that movie is inappropriate at that age.

Why would you want to? Why would he want to see it? (hypothetical) I don't even want to see it.
