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.
Somehow, I get the impression that you're not altogether awed by the writing on this show. I'm trying to keep it together, kind of keep the suspension of belief I use when viewing any Randy Orton match, but yeah.
