The Fast & Furious franchise is like a life preserver that keeps Vin Diesel's stardom from drowning. This time around, Paul Walker's super cop and Vin Diesel's super criminal have joined forces to pull off a $100 million robbery in Rio de Janeiro that somehow involves lots of street racing. Dwayne "The Rock" Johnson, for what it's worth, is the guy chasing them. The script feels like it was pulled randomly out of some producer's bottom drawer, but damn there's a lot of action. People with lots of decals on their cars should be happy.130 minutes PG-13.
