There's a whole plane take-off-crash sequence towards the end that you've probably got a glimpse of in the trailers. There's an intense chase through London in the initial reels and also a race later on. What works is the action - Lin and his crew bring us some of the most ridiculously outrageous and boldly conceived action sequences. Do the above statements sound cliché ? The movie's plot is full of such silly dialogs so its best ignored in the current context. Why ? Because the action makes up for all of it.
And at the expense of action, plot, writing, characters all take a backseat. Almost 20% of the movie is comprised of action sequences.
And the latest outing takes it a step further. Fast & Furious over the last few installments has become all about action.
