Piranha (2010) vs Drive Angry (2011)

"I am going to kill you, and then I'm going to defile your corpse."

One of the major differences between the exploitation films of the 1970s and what passes for exploitation cinema today is that such sentences appear in the scripts of the latter as dialogue and in the former as stage directions ("Jonah kills Piper and defiles her corpse").  When Jonah says these words in Drive Angry, the audience recognizes that the threat is an idle one.  In the exploitation films of the 70s such dialogue is unnecessary because the individual to whom these words would have been spoken has already been shot and the person who would have spoken them is already balls-deep in the bullet hole.
