How has the integration of MMA affected the mystical martial artist superhero?

Look at how films like John Wick, Kickboxer Vengence and potentially films like the Bourne series or Taken have taken the more modern approach to fight scenes, but still integrate the mystical or 'unknowable' martial artist that make the protagonist a superhero. How have these films shifted in the last 30 years? Are the protagonists existing in a superpower zone or more in reality than classic martial arts films?
