4. Copious Amounts of Spanking
Lots of repitition can make a film boring. Even if it is two hours of some eccentric billionaire spanking a hapless girl. Throughout the book Ana is subjected time and again to Christian's fetish for giving her a swat. Once again in a book we can see inside Ana's head and learn that for awhile she seems to enjoy this, but a movie... Well... All we're going to see is some dude smacking a girl. The more times we see it the more it will just get boring. Not to mention awkward. I wonder how the filmmakers will actually handle this particular aspect of the plot. Make it into a Benny Hill style running joke?
