Agreed, well placed and executed action or sex scenes can be used to great effect. They are also equally capable of adding nothing but wasted time. My point is that bad action scenes have been wasting plenty of time in movies lately, so a desire for tight films with no fat is definitely not the cause for the comparative dearth of sex scenes.
Don’t underestimate a raccoon’s intelligence. Put a half eaten burger in the world’s most secure safe, he’ll crack that mother and he’ll tell all his friends how he did it.
