Part 3. Exercise
This is a typical action film with lots of fight scenes and gun fights but little logic. It's amazing that hundreds of bullets can be fired at point blank range with no one getting hit and people getting hit in the face with fire extinguishers, pieces of wood and other objects without so much as a scratch. And then there are people surviving incredible explosions, again without getting so much as a hangnail. The directors attempt at moments of humor failed miserably. They were not only not funny but were very wierd to me.I enjoy watching John Cena in action, just as Arnold Schwarzenegger was fun to watch, but this movie just didn't impress me anymore than wrestling does. I think one star out of five was being too generous.
Answer:
Negative
