Pain & Gain is a guaranteed, 100% must-see. It's comical, thrilling, unexpected. It was perfect!! Fast the the furious on the other hand.. quite predictable, more-so on the theatrics.. It pretty much explains how all the other movies bunch up. Still, pretty sick cars this time around.
I didn't go see Pain & Gain but I loved Fast and Furious 6. I have seen all of them and so far have not been disappointed except for Tokyo drift.
