I saw A Good Day To Die Hard this past weekend.
There is an important distinction to make in my opinion:
1- As a movie, this failed spectacularly.
2- I had fun watching this movie.
Unfortunately, the Die Hard franchise has become a parody of what it once was. While 1988's Die Hard was a great action flick with good humor and a menacing villain (nobody ever out-did Alan Rickman), this one and the last one are basically meaningless shoot-em-ups where they need to be more and more outrageous than before.
Example: Die Hard featured Bruce Willis playing John McClane, surviving alone in a skyscraper as terrorists and criminals are holding his wife hostage. Skip forward 20 years. Live Free Or Die Hard featured Bruce Willis playing Bruce Willis, riding on the back of a jet fighter and blowing up a helicopter with a car, making quips as he goes. A Good Day To Die Hard is more of the same.
That said, these movies are amazingly fun. I laughed through much of it. Just so ridiculous. There is room for these mindless action films in cinema, but we need to treat them as such. Consider True Lies. On the one hand, a terrible film. On the other hand, you have Arnold Schwarzenegger (sp?) in a Harrier fighter yelling "Dana jump! Daddy will catch you!!!"
