Machete Kills really fails to keep the original idea alive. First off, the images are clean and modern, instead of the scratched effects used to simulate old b-movies type productions. Second, the story seems to take itself seriously at time. Third, we actually now have an action hero instead of anti-hero. Fourth, sex is much softer. It all ads up to a big disappointment.
Not worth seeing unless you're a really big fan of Robert Rodriguez or Machete.
