Very adult-oriented

Just watched it today and I noticed just how adult oriented it is

The husband and wife were about to go to bed together (as in having an early night)
There are several scenes where the next door neighbour is spying on the family trying to see where they got all that gold, the next door neighbour's wife thinks he's perving on the wife
The wife wouldn't go upstairs with one of the officers...because she wouldn't go upstairs with a strange man
