I am a HUGE fan of all things John Cena, whether it be is wrestling techniques, his music or his acting abilities, which could be better improved here, anyway i was amazed to come across this movie as i had no idea it existed! having seen his debut in "The Marine", and the fact that it was directed by Renny "Die Hard 2" Harlin i snapped it up.
If it's big bangs and exposive action sequences you're after then you can do no wrong with this, and if you can overcome John's weak acting abilities then you'll enjoy this. It kind of reminded me of Die Hard 3 but, in my opinion it is much better than that. There are some amazing stunt sequences and having seen the short docs follwing the film it's easy to see why John preferred to do all his own stunts, and it shows. It's no masterpiece but it is a blast from start to finish.
