I finally watched this movie and it wasn't that good. I agree with Myk JL, this movie had no actual plot. I thought Live free or Die Hard was a better movie.. After watching "A Good Day to Die Hard", I doubt there will be another Die Hard movie. This felt like a 'pass the torch to the new actor' movie, like "Indiana Jones and the Kingdom of the Crystal Skull."
And the trailers completely spoil the entire movie. Even the trailer's image in the youtube video in the first post of this topic gives away the entire ending.
