We may as well get it out of the way, if you liked the first 2 movies and Crank, then you'll probably like this, at the same time knowing its not as good as the previous 2.
The plot is fairly simple and nothing more than throwaway fluff. He must Transport a package and accompanying him upon his travels is a girl, and if either of them stray to far from the car then the bracelets they're wearing explode. So they've tried to add a new ingredient to the formula but it doesnt really make that much of a difference. In truth its only really utilised in 2 scenes.
Many people find his companion in this one annoying, but I thought she was okay. Rumours are that Statham wasnt happy with a previous director calling the character the first gay action hero, and the girl was put added to expel that myth. At one point she even asks "are you the gay?".
The rest is most of what you've came to expect. Again his shirt comes off during a fight sequence, some cool car chases, and some suspension of disbelief.
A mention should go to the main bad guy in this movie who most people will know as T-bag from Prison Break. He showed so many aspects of his character during 4 seasons of the show that there is nothing new to see, but he is still very good as the charismatic and ruthless business man, and its good to see him getting more big screen time.
The main negative for this movie is the Director who seems incapable of filming anything without multiple angles and numerous camera cuts. As a result a lot of the action and quality fight sequences end up being missed as its just too hard to focus. Just as you struggle to come to terms with the new camera angle it changes again a second later. Case in point a scene were Statham is just walking down the middle of a train, and I mean just walking, had something like 20+ cuts, and that was in like 30 seconds. It really does ruin the movie to a degree as most of it is pointless.
