Caught this with the wife yesterday. Incredibly fun movie, and worth watching on IMAX. Vin Diesel seemed to be channelling his inner Stallone for a good part of it (slurring words, massive fistfights) and it offered closure to a number of characters from 2 Fast 2 Furious and Tokyo Drift, but still left the door wide open for a sequel.
So on my nights off, I have been participating in G4/TechTV's new Hyperactive game on the Internet. It involves following the two shows on G4 from 11 to midnight, and going to the official website and playing the game.
