Went and saw it. Definitely darker and more serious than pretty much any Bond since From Russia With Love. If you're a fan of 'James Bond, Superhero', you might not like it as much as I did; This JB is human, even with the wild action. He gets hurt. He falls in love. He screws up. And when he operates...death or simple intelligence gathering....he's a blunt instrument, not a metrosexual playah.
I loved it. I left the theater buzzed and wanting to see it again.
