I long ago resigned myself to the fact that Nicolas Cage is a great actor who frequently chooses to appear in absurd movies, but I don’t think I like the idea of Eva Mendes following him down that path.
Sadly, the 'Ghost Rider theory' is proven here, in that the character, in look, design, and badassery, is the focus and the story is simply there to give him a reason to look cool, not exactly to make sense.
